Hawks, Snakes and Terns

We had another successful Sunday with the Young Naturalists group recently, looking at three very different aspects of the wildlife at Blashford Lakes. First we unpacked the overnight light trap, which is mainly used to keep a record of the moths on site, but the first insect out of the trap wasn’t a moth at all, but a cockchafer beetle (or May Bug, if you prefer). These large and impressive beetles are only on the wing for a few weeks each Spring, and this one was sufficiently sleepy to allow us to pick it up, and feel it tickle the hand as it tried to cling on.

Thanks to Fletcher for the brilliant head‐on photo. Most impressive of the moths was a Poplar Hawk Moth, and this time Fletcher gave us a profile photo. We also managed to identify Light Emerald, Treble Bar, White Ermine, Scorched Wing, Clouded Border, Nut‐tree Tussock, May Highflyer, and a couple of what we think were Orange Footman.

The rest of the morning was spent searching for snakes. A team of Blashford volunteers has laid out a number of tin sheets and felt squares for snakes and other reptiles to use. They are tucked away well hidden around the reserve, and only checked once a fortnight to minimise the disturbance for any snakes which might use them as shelters and places to warm up. We had special permission to lift a few felts and look underneath, and we had also heard that a baby grass snake had been spotted underneath a log in the Badger Wood area, when a visiting school had been on a search for minibeasts. So we were delighted when we turned over a log, and there was a small grass snake curled up underneath. Again, Fletcher was quick enough to capture a photo before the snake wriggled away into cover.
The photo also shows the snake’s nictitating eye membrane, a translucent protective cover over its eye. We found another four grass snakes under another of the felts, all of which looked to be youngsters, but they didn’t hang around long enough for a photo.

After lunch we headed over to the north side of the reserve, to have a look at places where adders have been seen basking in sunny spots in the undergrowth. We didn’t see any adders, but while we were out we took a look at the tern rafts which have been moored in the lakes to attract breeding Common Terns. The terns don’t seem to be in charge of the rafts on Ibsley Water, where the Black‐headed Gulls have taken over, but back on Ivy Lake we counted between 8 and 10 terns which appeared to be sitting on nests on the rafts. We also checked the rafts out on Ellingham Pound, where again the Black‐headed Gulls were in charge. While we were looking at them, Geoff spotted a Hobby, hawking above the trees, and we watched as it appeared to eat a dragonfly on the wing.

This month the Young Naturalists are meeting on Sunday, 26th June, when we will be joined by Claire Sheppard, a local photographer, and we will be getting tips on improving our wildlife photography. For more details, see:

Of moths and other insects, and a bit more besides…

I’ve fallen behind with my Young Naturalists updates, but since meeting at the reserve for the first time in April, enjoying the bird song and river dipping, we’ve been out onsite enjoying all the reserve has to offer, looking for reptiles, improving our moth identification, pond dipping and enjoying the insect life in the meadow. We’ve also been campfire cooking and improving the biodiversity of one part of the reserve by spreading wildflower seed. 

At the end of May we went for a walk on the northern part of the reserve, in the hope of finding some reptiles. We saw chiff chaff, blackcap and reed bunting and enjoyed listening to the reed warblers and Cetti’s warblers calling in the reed bed. 

We headed off into the reedbed to check some of the reptile refugia or felts used by the volunteers when they survey the reptiles. Our first sighting however wasn’t of a reptile, instead we found this caterpillar of the Oak eggar moth on top of one of the felts:

Oak eggar caterpillar

The hairy caterpillars feed on bramble, blackthorn, willow, hawthorn, hazel and other woody plants.

Under another refugia we were lucky enough to see our first reptiles, finding two adders. The first disappeared quickly into the vegetation, but the second stayed long enough for some of the group to get a good look and take some photos:

After leaving the reed bed we saw speckled woods enjoying the sunshine and watched the sand martins flying over Goosander Hide. We also saw a female adder basking on the bank by the hide.

After lunch we decided to pond dip, catching a very smart male smooth newt:

We also caught an impressive Emperor dragonfly nymph, which given the number of exuvia around the edge of the pond was a bit of a surprise, there were still more lurking in there!

The larva’s final moult takes place out of the water. As the adult dragonfly emerges from its larval skin, the cast skin or exuvia is left behind. It’s always fun to carefully look for evidence of their metamorphosis amongst the vegetation (and man made structures!) in the pond margins and the group had a good hunt, photographing their finds.

In June I had planned to spend the session focusing on insects, but with the weather so changeable we ended up adding in some campfire cooking as well. We began by looking through the moth trap where the highlight was this Poplar hawk-moth:

We also had a Buff tip, with its amazing camouflage, a very smart Muslin moth and a Burnished brass:

Rummaging through the moth trap didn’t take very long, and with the sun briefly making an appearance we hot footed it to the meadow before the showers came.

In the meadow we saw a small skipper butterfly, grasshoppers, a speckled bush cricket, a green leaf weevil and a green-eyed flower bee enjoying the selfheal.

We also saw a number of Thick-legged flower beetles, also known as swollen-thighed beetles and false oil beetles. They are often seen on the flowers of ox-eye daisies and other open-structured flowers and only the males have swollen thighs:

The meadow and the lichen heath are both covered in Perforate St John’s-wort at the moment, it is having a really good year. Traditionally it was used as a remedy for all kinds of ailments, including wounds and burns, and is still popular today for the treatment of mild depression. Research and opinions however differ on how effective the latter is.

It can be identified by its bright yellow star shaped flowers and the tiny ‘holes’ in its leaves. The holes are in fact colourless glands that apparently give off a foxy smell. If you hold a leaf up to the sun, the tiny holes are easy to see, but they’re definitely more obvious on a sunny day!

After a short while in the meadow, we headed back to the Centre collecting nettle tops on the way to make some nettle soup. We also picked some mint and lemon balm from around the pond to make tea. After gathering the kit and our lunches, we headed to the campfire area.

Alex decided to toast his sandwich and after eating we boiled some water for the tea and made our soup. Both had mixed reactions, although to be fair some teas did contain nettle, mint and lemon balm and we possibly gave the wrong person the nettles to wash… so our soup did contain a number of less welcome additions!

July’s session was also influenced by the weather. I had planned to do the Big Butterfly Count with the group last Sunday, something we have participated in with them for the last few years. The UK wide survey is running until the 8th August, so there’s still time to take part if you would like to, you just need 15 minutes and a sunny spot…

Thankfully, moth trapping has improved over the past few weeks, with more species and numbers of moths coming to the traps, and we were able to spend the morning having a good look through and identifying most of what we found.

Identifying moths

Common Rustic

Daisy made a list of those we were able to identify (we lost a few on opening the traps and some of the micro moths did stump us) and we managed to record 70 moths of 39 species in the first trap and 63 moths of 28 species in the second trap. Both traps were close to the Centre, with one positioned out the front towards the mini meadow by the Welcome Hut and the other positioned out the back of the building.

Our grand total from the Saturday night was 133 moths of 52 species. Here are some of the highlights:

The Large emerald in particular proved popular:

After lunch, we went back to the meadow to see if the Bird’s-foot trefoil had gone to seed. If it had, we were going to collect some to add to the other seed we had from Bob to sow, but unfortunately it wasn’t quite ready. We did see a Common blue butterfly resting on a seed head:

We then went looking for wasp spiders on the lichen heath, managing to find two in amongst the soft rush. Their colours mimic the common wasp, keeping them safe from predators.

Wasp spider

Wasp spiders build large orb webs in grassland and heathland. Their webs are quite distinctive, with a wide white zig-zag running down the middle known as a stabilimentum.

After some impromptu boat making by Kimberley and Harry, we stopped off at the river to see whether or not their boats would sail:

We then began our seed sowing, adding Bluebell seed in amongst the hazels to the side of the path between the bridge over the Dockens Water and the road crossing to Tern Hide. We swept away the leaf litter and put the seed thinly on the soil surface, before brushing the leaves back over to cover them.

We then crossed over the road towards Tern Hide and went through the gate to the part of the site currently still closed to visitors. This was once a concrete plant, and when the plant was demolished we began restoring the area, including the old main entrance roadway. Although it has taken time, this spot is now well colonised by lots of plants and our addition of some extra seed will hopefully help improve it even more. 

We added Wild carrot to the driveway, scattering it thinly onto patches of bare ground, Devils-bit scabious up on the bank as it prefers a deeper soil and Jack-go-to-bed-at-noon on the same bank, poking each seed individually into the ground using a pencil (we also saved some of these for the mini meadow by the Welcome Hut). Finally we also added Yellow rattle seed and some assorted hawkbits and crow garlic.

Fingers crossed some of them come up!

30 Days Wild – Day 4 (a bit late!)

I was not able to do the last couple of days at the time, but here is Friday, spent at home mostly, but that did not mean without wildlife. One of the first things I did when I moved in was to set aside a section of the lawn to see what was in there. It turned out mostly grass, no surprise there, but also red and white clover, small stitchwort, cat’s ears and quite a bit more besides. To this I added some local seed and a few plants I grew on myself and planted in. Now I have quite a nice mini-meadow.

OLYMPUS DIGITAL CAMERA

It is noticeable how many insects there are in the mixed flowers and grass compared to the remaining traditional area of lawn. It probably also help with the diversity of moths I catch in the garden. On Friday the highlights were a coxcomb prominent

Quiet a common species, but this was the first one I had seen this year. The prize for the largest moth went to a privet hawkmoth, which is our largest resident species.

Whilst the top spot for scarcity went to a ringed carpet, this is primarily a northern species but there is a southern population more or less restricted to the New Forest.

30 Days Wild – Day 3

I had high hopes for the moth trap this morning and I have to say I was a little disappointed, so rather than a moth, my insect from the trap for today is a true bug, a striped plant bug, proving once again that it is not only moths that are attracted to moth traps.

striped plant bug

Outside the Centre at Blashford we have a number of planters filled with plants chosen to attract insects. It is not just the plants that can attract then though, we also have a number of wooden posts with holes drilled in them which are used by nesting bees and especially mason bees. At this time of year the species using the largest holes is the red mason bee. These bees, about the size of a honey-bee make cells for each larva which they provision with pollen and then seal up with mud.

red mason bee

Around the Centre the gravel has been colonised by lots of plants that do well in well drained conditions, such as marjoram, dark mullein and hedgerow cranesbill.

hedgerow cranesbill

Where it is less trampled and perhaps not quite so dry the vegetation is taller and at this time of year the bright flowers of green alkanet are very obvious and popular with several of the smaller bee species.

green alkanet

Both this plant and the cranesbill are believed to be old introductions to this country from the near continent. A fair bit of out flora has been imported, by accident or design, much that has come from just across the Channel has settled in and now lives like a native. These species have often come with their own insect and other controls and so don’t get out of hand, unlike some introductions from further afield which have often left their escaped their natural controls, which is why they can do so well and out compete native species.

30 Days Wild – Day 2

A much warmer night after a couple of sunny days and now there are more moths appearing in the trap. My highlight at home was a rather beautiful alder moth, the adult is fine and the caterpillar, if you can find one is magnificent, try a web search and see if you don’t agree.

Alder moth

Whilst alder moths are not that frequent in the trap, one of the commonest species is the light brocade and I caught several both in my garden and at Blashford Lakes. The name of this moth harks back to the Victorian days of mothing, when brocade would have been a familiar material.

Light brocade

One of the fascinations of Blashford Lakes is the wide variety of habitats within the reserve. There is a lot of water, both in the form of the lakes themselves and the small Dockens Water river, but also various pools and puddles of various levels of permanence. At the other extreme we have a lot of very dry, sandy habitats, almost all derived from the left-overs of the gravel industry. These dry habitats have lots of rare and interesting species, one I was shown today, that I had not previously seen is shepherd’s cress.

It is similar to the familiar shepherd’s purse, although I confess I do not seem to see that as frequently as I used to. A lot of these rare plants of the dry habitats are small and unprepossessing, they cannot compete with more vigorous species and thrive only in very nutrient poor habitats. An increasing and rather unreported problem is the increase in nutrients falling in rain, particularly nitrogen, which enriches the soil eliminating these specialists of nutrient poor places.

A muggy night ahead with the promise of lots more moths tomorrow, so long as we don’t get too much rain, I may have to get up early in the morning to check the traps.

30 Days Wild – Day 1

It’s that time of year again and after a rather slack time for blogging I will try an pick up the baton again. Although we are moving close to Mid-summer’s Day, it actually still feels quiet spring-like, despite the weather having finally turned warmer. So I will start with bluebell, still in flower in lots of places at Blashford Lakes, although just starting to go over in places.

Bluebell

Ferns are a feature of the woods around the Centre, especially those self-sown on the old spoil heaps left by the gravel workings. Perhaps the least “ferny” is the hart’s tongue fern, which completely lacks the pinnatifid form that is normally associated with a fern

Hart’s tongue fern

Despite getting warmer the moth trapping remains very poor, but the trap does not only catch moths, one of last night’s non-moths was this rather cute looking brown lacewing, I am not sure of the species as they are rather difficult to identify in life.

Brown lacewing

Warm and dry conditions at this time of year can result in “snowfall” at Blashford, or at least that is what it can seem like, as the willow seed is shed in clouds and collects in drifts along the paths.

Seeding willow

Having said the moth trapping has been poor, I did catch one rarely seen species last night in my garden trap, a buttoned snout, not a lot to look at perhaps, but a new record for my garden. It had been though they were in steep decline, having been regularly found by earlier naturalists. However it seems our modern reliance on light traps for recording moths maybe to blame. They do not often come to light, so were considered scarce, but if you look for the caterpillars, as entomologists did before they had light traps, it turns out they are not so hard to find. How you look is important, especially if you want to infer change.

Buttoned snout

A different view

On Tuesday I accompanied Bob to the north eastern shore of Ibsley Water so he could fell some of the willows into the lake, creating perches over the water for birds like heron and egret to fish from. I did fell a few smaller trees, but admit I was mainly there as first aid cover and did make the most of the opportunity of being in a different spot, enjoying a wander along the edge of the bay where I’ve only been once before.

Whilst we were up there, a goosander flew overhead and a couple of pied wagtails made themselves comfortable on the osprey perch:

On the walk back I noticed some blackening waxcaps on the edge of the lake near Lapwing Hide, which were beginning to change colour. A grassland fungi, blackening waxcaps turn black with age, hence the name, but prior to blackening they can be red, orange or yellow in colour.

There is plenty of fungi in accessible locations on the reserve, with candlesnuff fungus seemingly everywhere if you look closely enough at the woodland floor along the footpath edges:

I also found a couple of earthfans on the edge of the lichen heath. They can be found on dry sandy soil and have a rosette like fruiting body which is usually reddish brown to dark chocolate brown in colour.

Earthfan

There were also a number of russula growing in amongst the lichen. There are approximately 200 russula species in the UK and the generic name means red or reddish. Although many have red caps, many more are not red and those that are usually red can also occur in different colours. This species could be Russula rosea, the rosy brittlegill, but I’m not completely sure so will stick with the genus russula on this occasion!

Russula species in amongst the lichen

There was also a branch covered in jelly ear fungus along the ‘Wild Walk’ loop, close to the acorn sculpture:

Jelly ear fungus

Also known as wood ears or tree ears, the fruiting body is ear shaped and is usually found on dead or living elder.

With the colder, wetter weather we have begun to get a number of more unwelcome visitors in the centre, usually wood mice or yellow-necked mice. Although we enjoy catching small mammals as an education activity, they are less welcome additions to the centre loft where they have in the past chewed through the cables. So we trap them in the loft too, using the Longworth small mammal traps, and safely relocate any we do catch to the further reaches of the reserve. On Sunday morning there were two mice in the loft, so I took them up to Lapwing Hide and released them into the undergrowth.

There have been a good variety of moths in the light trap recently, with the highlights including mottled umber, streak, red-green carpet, green-brindled crescent, feathered thorn and December moth:

Although I haven’t seen any sign of the brambling recently, the feeder by the Welcome Hut is being regularly visited by at least one marsh tit. We had a pair around the centre regularly over the summer so it has been really nice to get great views of at least one feeding frequently.

Marsh tit

Starling numbers have been increasing and on Tuesday evening there were several thousand north of Ibsley Water. They are best viewed on a clearer evening from the viewing platform which is accessible on foot through the closed main car park and gives panoramic views of Ibsley Water.

Ibsley Water from the viewpoint

This is the perfect spot to watch the starlings put on a show as they twist, turn, swoop and swirl across the sky in mesmerising shape-shifting clouds. These fantastic murmurations occur just before dusk as numerous small groups from the same area flock together above a communal roosting site. The valley boasts a sizeable starling murmuration most years, with the reedbeds to the north of Ibsley Water often used, along with those on the other side of the a338 to the west and the smaller reedbed by Lapwing Hide in the east, so from this higher vantage point all possible roost sites can be seen. 

Although I don’t have any photos to share of the murmuration, taking a video instead the last time I watched them, it’s also a really nice spot to watch the sun set.

The Blues

Cooler wetter nights are resulting in large declines in moth numbers now, but this time of year is the main flight period of the Clifden Nonpareil at Blashford and over the past few days we have caught four. It is a really big moth, with wings closed a lightly patterned grey, but if the hind -wings are flashed quite different and you can then see why it is also known as blue underwing.

Clifden nonpareil

This year had been a record one for this species in the UK, or at least a record in recent decades, with lots of records during September from a wide area of southern England. This moth was locally resident in England until the early part of the 20thC when it died out and became just a very rare migrant. Over the last twenty years or so it has slowly recolonised, especially in the New Forest area. We have been catching them regularly at Blashford for a few years now, mostly in October. I suspect a lot of the ones caught earlier are migrants from the near continent.

Wherever they come from they are spectacular moths and I remember seeing them in the moth book years before I ever caught one and thinking how amazing it would be to see one. Even though I have now seen quiet a lot of them I can confirm that it was and still is amazing to see them.

Greens

The cool autumn nights see rather few moths flying, but those that are around include some of the most attractive of the year. A personal favourite, as I have posted beforen (several times!), is the Merveille du jour, with its black, white and green colour scheme, there was one particularly fine one in the Blashford trap this morning.

merveille du jour

A lot of autumn moths are yellow or brown, presumably as camouflage as the leaves change colour, but there are also several with shades of green. The merveille du jour would be well hidden on a lichen covered tree, whereas the green brindled crescent might do better in the vegetation.

green brindled crescent

Although the moth traps with their ultra-violet light attract most of the moths it is also worth checking the security lights and today the one at the Centre door had attracted a micro moth Tinea semifulvella, a species with caterpillars that eat organic debris in places like old bird nests.

Tinea semifulvella

The trap attracts various other insect as well, most conspicuously caddisflies. Unfortunately these are harder to identify and I have never spent much time trying to name them, although I do have an identification key, but it takes time to get started on a new group and I never seem to have any of that to spare.

Halesus sp. caddisfly

At least I am pretty confident about the genus of the one above, I have not even got that far with the one below.

caddisfly

Over the last few years the alder trees that used to line the Ivy Silt Pond have been dying or otherwise have needed to be felled, gradually opening up the view from the footpath. The aim now is to try to open up the view along as much of the path’s length as possible. This does make it easier to see the birds on the pond but, more importantly, it makes it easy for the birds to see us. Wildfowl on water feel quite safe, even if there is a predator about, so long as they know where it is and know they can escape if they need to. In this case we are the potential threat, but if we can be seen and are a safe distance away that is probably okay. By cutting the bramble to about waist height they can easily see we are behind the hedge but can easily follow where we are as we go down the path. In this way they are likely to habituate to the presence of people, but it does take time.

Opened up view of Ivy Silt Pond

I was delighted this morning to see 24 mallard. 2 gadwall, 2 teal and a wigeon on this pond, what is more all, apart from the teal, stayed feeding quietly as I walked by. Habituation would be my preferred option throughout the reserve if it were possible, it offers more opportunity to see the wildlife, but it does depend upon the separation between people an wildlife to be very predictable. It works well on coastal sites with deep ditches or mudflats separating viewer from the wildlife, such as is found at Farlington Marshes or Lymington/Keyhaven Marshes. Contrary to what you often read walking on the skyline is actually a good thing on these sites as the birds can always see where the people are and know that if we are on the top of the seawall we are not a threat. Perhaps unsurprisingly wildlife likes to feel safe and avoids unpredictable situations. One way to accommodate more wildlife into our lives is to understand this and plan accordingly, we could have a lot more space for wildlife without actually needing more physical space, all we need to do is think about how we design and use the space we share.

Saved by the moths…

We have been running our fortnightly Young Naturalists catch-ups now since the the end of May and, seven catch-ups in, they are keeping me on my toes in terms of content. Although shorter than a normal on site meeting, making sure we have plenty to discuss for the whole two hours online has kept me busy, collating their photos so we can share them with everyone during the session, catching pond creatures beforehand so we can look at them under the digital microscope, and putting together presentations on other topics, chosen by them and generally not my area of expertise!

I have fallen behind with my Young Naturalist blogs but August’s sessions focused on dragonflies and damselflies (thankfully I now have a good number of photos of different species which made putting together a presentation quite easy)…

Life cycle of a dragonfly and damselfly

…and owls (thankfully the Trust’s image library has a number of fabulous photos of owls that have been taken by other members of staff or sent in by very generous photographers, along with their permission for us to use them)…

Owl presentation

Other birds of prey have also been requested, so the image library will be coming in quite handy again at some point… 

It is always a bit nicer to look at something living though, so at every session we have had one if not two light traps to rummage through and volunteer Nigel has also run his trap at home to add to our moth chances. With the exception of a few cooler nights, we have had a great variety of moths to look at, they have become a regular feature! 

Here are the highlights from the last couple of sessions, plus possibly a few that were caught in between:

Sticking with the moth theme, this morning there were a pair of Burnished brass in the trap, unmistakable with their brassy, metallic forewings. There are two forms of this moth, which differ in the brown central cross-band which is complete in f. aurea but separated into two blotches in f. juncta. 

Burnished brass, f.juncta on the left and f. aurea on the right

We haven’t just been catching moths in the light trap, but also lots of caddisflies, shield bugs, beetles and this rather smart looking Eared leafhopper:

Eared leafhopper

They can be found on lichen covered trees, in particular oaks, but are incredibly hard to spot due to their amazing camouflage.

Fingers crossed for some mild September nights so we have some nice autumnal moths to identify for a little longer, or we may have to get into caddisfly identification…

Elsewhere on the reserve the dragonflies continue to be very obliging, with common darter and southern and migrant hawkers perching on vegetation behind the centre to be photographed – the migrant hawker below was pointed out to me by regular visitor John:

Migrant hawker

This morning large numbers of house martin were gathering over the main car park by Tern Hide and Ibsley Water, in preparation for their incredible migration to Africa, whilst the shoreline has also become busier, with an increase in wagtails over the past few days.

Yellow wagtail

Pied wagtail

Juvenile Pied wagtail

Yellow wagtails are summer visitors and they too will head to Africa for the winter. Most Pied wagtails are residents however those that occupy northern upland areas will head south for the colder months, boosting the populations already found in the warmer valleys, floodplains and on the south coast. They can migrate as far as north Africa to escape the cold.
