We’ve Got the Blues, Again

Tomorrow I have a moth event at Blashford, we will be opening two moth traps and looking through at the catch, identifying and photographing them. Over the last few days we have caught three Clifden nonpareil moths, also known as the blue underwing, this is a spectacular species and probably the UK moth with the largest wing area. In fact there was one yesterday and another today, obviously it would be great if there was one tomorrow, but things being what they are I suspect there won’t be! It is also still quite rare nationally, having only recently recolonized the UK, luckily for us the New Forest area is probably their stronghold.

The caterpillars feed on aspen and probably other poplar species, as it happens we have a number of aspen at Blashford Lakes, which is probably why they seem to be established on the reserve. Aspen is an interesting tree as is has quiet a lot of insect species associated with it. It is a tree that can grow very tall, but also produces lots of suckers, so there can be niches for species that prefer the canopy and shrub layer provided for by a single tree. It is very prone to being browsed and the suckers are often eaten off, increasing numbers of deer are probably one reason that aspen is in decline in many areas.

We may not see a Clifden nonpareil, but I hope we will see a good few moths and one thing that I am fairly sure about is that a number of them will be yellow or orange, autumn is the season for yellow moths, probably because it is the time for yellow leaves.

Although autumn is well underway now there at still quite a lot of insects about when the sun comes out, southern hawker, migrant hawker and common darter dragonflies are still around in fair numbers and butterflies include red admiral, comma and a lot of speckled wood. As I was eating lunch yesterday I noticed a fly on the picnic table next to me and realised it was one of the snail-killing flies.

It is the larvae that kill the snails, in the case of this species , aquatic snails, which is probably why it was close to the Education Centre pond.

Roasting and toasting

It was rather warm on Sunday for our August Young Naturalists gathering, so we decided to roast ourselves even more by spending time in the meadow, a habitat we haven’t really visited yet this year, followed by a bit of blackberry bread cooking over the campfire…

We began though with a look through the light trap which revealed at least 19 different species including a lovely Peach blossom, a Purple thorn, a Pebble hook tip and a Chinese character, amongst others.

We were then distracted by a Southern hawker flying over the pond, which Talia managed to photograph whilst it was busy hawking for insects:

After gathering up some sweep nets, identification sheets and bug pots we made our way over to the meadow in search of wasp spiders, grasshoppers and bush crickets and anything else we could find. It didn’t take us long to locate the wasp spider, just inside the gate on the left hand side.

I set the group a challenge to find a pink grasshopper and a Roesel’s bush cricket. I don’t think they believed me about the pink grasshopper, but once they’d spotted one they tried their best to catch it and find more, but without any success! So sadly no photo!

Most grasshopper species are a more sensible green-brown colour, allowing them to blend in with their surroundings, but some do carry genes that make them pink or purple-red. They just might not survive for long in the wild (or stay in one place long enough for a photo!), as they are more likely to be predated. The group did now believe there were pink grasshoppers though, and there were plenty more sensibly coloured ones around that didn’t move quite as fast for us to catch and look at closely.

As for the Roesel’s bush cricket, although we swept through the grass outside the meadow as well as in it, we couldn’t find one, so I will have to be content with the photo Bob put on the blog yesterday instead. We did though catch a very fine looking female long-winged conehead cricket instead:

We also found a number of other spiders, including some brilliantly patterned orb web spiders and a wolf spider, alongside caterpillars, an orange swift moth, common blue damselflies, honey beesbaby toads and more.

After getting a bit hot in the meadow, we relocated momentarily to the shade and picked blackberries before heading to the campfire area to attempt a bit of bread making. Megan and Will H did a superb job of mixing us up some dough whilst Will S and Ben helped lay the fire which Ben then lit.

I offered the group blackberries, dried fruit, freshly picked marjoram and chocolate buttons for their ingredients, which seemed to cater for all tastes, and we had a mix of fillings and shapes on the grill – not everyone opted for chocolate! Everyone went back for seconds…

The group enjoyed bread making so much they requested more campfire cooking, so we agreed on a winter cookout towards the end of the year, the food list is already quite lengthy!

We also found time to hunt here for minibeasts, finding a flat backed millipede that managed to stay still long enough for Talia to take a photo and a ground beetle larvae.

Thanks to volunteers Geoff and Roma for their help on the day and to Talia for taking lots of great photos and sharing them with me for the blog.

Wider Views and New Surfaces

It seems to have been a week with a lot going on, the phalarope’s three day stay has pleased the birders, although it has now left us. Meanwhile we have been clearing fallen trees from near Ivy North which should please everyone who uses the hide as it should be possible to see quite  a lot more. Further and perhaps even more widely welcomed, will be the news that the main track to the Centre and path to Ivy North and Woodland hides have been improved with a newly rolled surface.

The view from Ivy North was:

Although the phalarope has gone and I managed to miss the reported osprey, garganey and common swift, my day was not entirely without wildlife. We had lunch accompanied by our regular, and now very smart looking robin.

There was also a fine southern hawker flying about us and it briefly landed, allowing a quick shot.

The last few nights have been very warm and numbers of moths have picked up, although the range of species has not been that large. A few autumn species are starting to show up, with rosy rustic and pink-barred sallow a sure sign of the moving seasons.

 

Mothless, well Almost

Yesterday I ran a “Moth event” at Blashford, unfortunately I forgot to tell the moths and there were probably more human participants than moths! Usually late August is a good time for catching large numbers of moths, but big catches require warm, calm nights following warm settled days. What we had was a windy, mostly clear night following a rather stormy day.

Luckily the day got more settled as it went on, at least until late afternoon anyway. This brought out good numbers of insects, including as many dragonflies as I have seen this year. Around the reserve I saw several brown hawker, southern and migrant hawkers, an egg-laying emperor dragonfly and a fair few common darter. Damselflies included common blue, azure, red-eyed, small red-eyed and blue-tailed.

Butterflies were rather fewer, most that I saw were whites, with all three common species near the Centre. Out on the reserve a few meadow brown and gatekeeper are still flying and speckled wood are increasing again. Near the Lapwing hide I saw both red admiral and painted lady, perhaps indicating some continued arrival of passage insects.

The sunshine in the middle of the day brought out reptiles as well and I saw two grass snake and an adder. The adder was very fat and I suspect a female which will shortly be giving birth, since adders have live young rather than laying eggs as grass snakes do.

I have heard reports of wasp spider being seen around the reserve recently and today I finally saw one.

This is a female, the males are much, much smaller and wander about seeking the females.

I had hoped for a few different birds, following the rough weather, perhaps a few terns, but there was little change form the past week. A few extra waders were the best that could be found, 2 dunlin, 2 oystercatcher, 2 common sandpiper, 1 redshank and the pick of the day, 3 greenshank, although they only flew through. There are starting to be a few more ducks around, I saw 8 shoveler and 3 teal, but there are still no wigeon on the reserve, although they should not be far away. Away for the water looking up there were 2 raven, and single hobby and peregrine. Whilst low over the water before the day warmed there were 1000+ sand martin and c200 house martin.

Perhaps the sighting of the day for many visitors though was the female roe deer that spent part of the morning in front of the Woodland hide.

A Good Day for Grasshoppers

It was my turn to be on site on Saturday again and after dealing with some office work I took advantage of the good weather to have a look for some insects. I used to get out occasionally to do a bit of wildlife recording like this, adding to the reserve species list, but somehow time to do this has ebbed away over the years. It was a real treat to spend a while just looking at things.

I was rewarded with a good selection of grasshoppers including lots of the tiny mottled grasshopper.

I then had a real stroke of luck and found a new species for the reserve, perhaps not an entirely unexpected one, as it is common in the New Forest, but something I had looked for previously and failed to find. It was a very smart woodland grasshopper, one of my favourite species, with a black and red body and brilliant white palps, which unfortunately this picture does not show.

The lichen heath used to have a string population of the bee wolf, a species of wasp that preys on bees as large as itself. As the heath has slowly vegetated there are fewer sandy patches, where they make their burrows, so now there are many fewer, but they are not all gone.

Other species I came across included another tumbling flower beetle, although I have yet to identify this one, there were several of them on this one tansy plant.

Apart from a good showing of insects the reserve was quiet, despite being warm there was a distinctly autumnal feel to things. I could find no little ringed plover around the shores of Ibsley Water, so perhaps they have started their trip south. The swift have certainly done so, I saw only two all day. The common tern have also almost all gone, just one family seems to remain.

I will end with one last insect, my first southern hawker of the year, not a great picture, despite getting quite close to it.

Bank Holiday blues

Welcome, from a soggy Blashford Lakes Reserve. As is customary we have another damp and dismal Bank Holiday Monday (10mm of rain overnight and it hasn’t stopped raining all day), but there are a few folk here making the most of the situation.

Not terribly inspiring for bird watching and most self respecting insects are keeping well out of sight today, so I’ll just share a few pictures, taken last Friday, when covering the Butterfly Survey transect on the south of the Reserve.

Green-veined white butterflies were the most common on the transect and arguably THE most common butterfly in the U.K. with a wide geographic range (absent only from Orkney and Shetland) and having two or even three broods (in good years).  An innocuous butterfly, its caterpillars don’t damage cultivated cabbages, unlike their close cousins the large white  and small white, but lay their eggs on wild relatives of these plants. An active butterfly its quite difficult to identify from small white when in flight, I’m guessing that many ‘non-butterfliers’  probably wouldn’t even have heard of them – I know I hadn’t before taking more interest in these insects.

Most common butterfly - Green-veined White

Green-veined white butterflies are very much a species of damp and marshy places near hedgerows and woodland edges, so the Reserve is ideal habitat for them – especially today.

Overall the number of butterflies to be seen has dropped off lately as the temperature falls  and sunshine has decreased with only 21 butterflies of four/five species ( including ‘unknown’ White) seen last Friday, although I believe the transect on the north side of the Reserve was more productive. The brightest and  most colourful was this Comma.

Comma - so named from the tiny white 'comma shaped' mark on the underside of the hind wing

Comma – so named from the tiny white ‘comma shaped’ mark on the underside of the hind wing

The common name of this butterfly, and even the scientific name Polygonia c-album, refer to this tiny mark (if my rusty knowledge of Latin is correct c-album = ‘ white c’), but it’s really quite inconspicuous unless you know to look for it.  I guess the naming dates back to the time when collectors could study these things at their leisure as it was  ‘O.K.’ to catch these beautiful insects and handle them, before killing and mounting them in collections

In greater profusion than all the butterflies were common blue damselflies which were just about everywhere, gently skimming over the tops of shrubbery and settling, usually briefly, before being disturbed by another damselfly. The males were most conspicuous, with their electric blue colouration,  whilst the females were difficult to pick out, especially if motionless as they stayed perched up.  I’ll admit that I find it easier to identify the species of a male damselfly, like ducks as opposed to drakes, the females are more drably marked.

Dragonflies and damselflies are spectacularly visual insects, the relative size of their eyes is a bit of a give-a-way, so I’m guessing that males can easily identify their prospective mating partners from a mixed assortment of, to us, similar looking females of other species.  As a safeguard to prevent cross breeding  I understand that the claspers (anal appendages) on a male can only latch on successfully to the neck of a female of the same species to create the mating position called the ‘heart’ or ‘cartwheel’ position.  Whilst so engaged they are easier to photograph as they seem somewhat ‘distracted’ and less likely to fly off suddenly – can’t think why!

Dragonflies were also out and about, hopeless trying to photograph them whilst flying (the dragonflies – not me!) with my little camera, but when they hang-up briefly there’s a chance of a quick shot.   Missed the southern hawker, but this migrant hawker was more obliging.

Common darter are living up to their name, by a) being quite common (20 plus seen easily – don’t know how many we missed) and  b) perching up and ‘darting’ out before returning to the same perch, making them relatively easy to photograph.

The butterfly transect should notionally take about an hour and a half, but we managed to stretch it to two hours, having been ‘distracted’ by some quite delicious blackberries along the way. Whilst engaged in this activity a strange bug hopped onto my hand and demanded to have it’s picture taken.

Dock bug?

Dock bug?

Searching the literature – and online – I think its a dock bug (Coreus marginatus) , though not a fully grown one, as these appear to have a more definite darker patch on their abdomen.  One of the family ‘Leatherbugs’ of which there are eleven species in the U.K. and five in the new Forest (Paul D. Brock : A photographic guide to Insects of the New Forest) this is apparently the most common and easily found.

I’ll close with an update from the rain gauge – 22mm (nearly an inch in real terms)  and rising!!

 

Pictures from the Purple Patch

It’s often been said, ( although, probably only  by me!) that a lot of the conservation work at Blashford is  ‘ a bit like gardening, but on an industrial scale‘ .  Today I was doing what, to me,  is one of the more pleasant gardening tasks of dead heading the buddleia.   We don’t have much buddleia left on the reserve, it’s a terribly invasive non-native plant and as such doesn’t really belong here so it’s largely being eradicated from the more wild parts of the reserve, with only one plant left near the Centre.  It is, however, a great nectar source for insects and removing the seed heads encourages more flower to form.  So what could be finer on a pleasantly warm day than a little light pruning whilst seeped in a heady fragrance and being constantly visited by comma, small tortoiseshell, green-veined white, silver-washed fritillary and peacock butterflies and also this smart red admiral.

The rich lilac/purple flowers of the buddleia are mirrored by many other flowers at the moment – indeed the reserve is going through a ‘purple patch; as evidenced by the flower-heads of creeping thistle, teasel and marjoram

After my embarrassing faux-pas over the bee/hoverfly last week ( thanks to those who put me right) I’m reluctant to put a name to this  —  I just know there are really knowledgeable folks out there who can tell us.

And a final flourish was this rather posey small tortoiseshell who insisted on sharing a pick-nick bench with me.

As I say all this from, almost, a single position – can’t be bad…

Oranges and Lemons

After a three week break of duty, it made a pleasant change to be opening up the reserve and be greeted by a common sandpiper immediately outside the Tern Hide.  Ibsley Water bore  its usual compliment of waterfowl. Mute swans were much in evidence, not only as their physical presence, but from the large scale scattering of innumerable moulted white feathers floating across the lake.  Duck numbers are building up with representatives of several species including gadwall, tufted duck, wigeon,  mallard and shoveler. As usual at this time of year it can be quite difficult to sort many of them out as the usually distinctive drakes have moulted into a somewhat drab ‘eclipse’ plumage, similar to the females.  This is thought to be a survival mechanism, making them less conspicuous whilst they moult their flight feathers. Large numbers of lapwing are now making use of the shingle spit to the east of the tern hide and are accompanied by several (we counted fourteen) Egyptian geese.

Although we are still experiencing warm weather the numbers of insects have dropped dramatically since I was last here. A male Southern Hawker dragonfly was periodically patrolling the pond behind the Education Centre, but only a few large white butterflies and a red admiral were much in evidence.

The moth trap hasn’t been set out  much lately, but Jim kindly put it on for us last night.  Our reward was some seventeen species of moth, but the downside was  a fairly large number of wasps – sorry don’t know what species – plus a couple of LARGE hornets, which made emptying the trap somewhat challenging…
