Garden Highlights

I seem to have been very busy recently, a couple of days away and evenings spent out surveying nightjar have left no time for blogging. The last few days have produced a few notable species in my garden which I will cover, a Blashford update will have to wait a bit longer I’m afraid.

The other day I recorded my first silver-washed fritillary in the garden, it was on a Buddleia, the “butterfly bush”, I do not grow the common davidii, which seeds freely and can be an invasive species in dry habitats. To avoid the seeding risk I grow a sterile hybrid known as Buddleia weyerianait may not be quiet as attractive to insects, but has the advantage of a much longer flowering season.

The moth trap has been productive as well, warm nights are always good for moths and we have had lots of those recently. The pick of the recent catches has been a very smart mocha, caught a couple of nights ago.

Followed last night by a Jersey tiger, this splendid looking moth used to be found only along the south coast of Devon, but in recent years has become established on the Isle of Wight and very recently along the southern edge of the New Forest too.

The Heat Continues

After a June and 30 Days Wild which was extremely hot and the met office now tells us was the driest on record we have now hit July and things are not changing. I did see some cloud on Sunday, but all it seemed to do was increase the humidity.

The heat is making it difficult to work, despite this on Sunday five volunteers turned out and we pulled Himalayan balsam for an hour and a half, a remarkable effort. On Monday I saw removing ragwort from the areas I plan to mow on the shore of Ibsley Water.

All this heat continues to be very good for insects, the moth catch overnight on Sunday/Monday was the highest I have ever had at Blashford, one trap caught 96 species! This included a lot of micro moths, many of these are quite spectacular looking, but it is hard to appreciate what they really look like as they are so small.

The one above is actually quiet common and I see it fairly regularly. I did catch a few new species for the reserve including a chalk grassland species that feeds on marjoram, a plant which does grow in the gravel near the building, so perhaps it was a local rather than a wanderer.

There are lots of butterflies and dragonflies around the reserve. Silver-washed fritillary are having a good year and gatekeeper are now emerging as are the summer broods of small copper and brown argus.

Brown hawker and southern hawker dragonflies are both already flying in some numbers, although common darter are still quiet few.

The picture above was my best of a few attempts at getting a flight shot over the Centre pond at Sunday lunchtime. At the same time I saw a large red damselfly that had fallen into the pond and been preyed upon by a water boatman.

When you are an insect there are many ways to die more or less everything is out to get you! There are predators and more gruesomely parasites almost everywhere. I found a parasitic wasp hunting for a beetle larva in which to lay its egg.

The needle-like ovipositor can be pushed deep into the wood, when not in use it is protected by a sheath, in the picture you can see the ovipositor in use probing almost vertically downward.

The dry weather is stressing plants and some smaller trees are losing their leaves already. Most of the grass is now brown and many species rapidly going to seed. There are still flowers out there though and one such is creeping cinquefoil.

30 Days Wild – Day 24 – Up on the Downs and Down by the Sea

We travelled up to Martin Down in the morning, specifically Kitts Grave the part of the reserve that belongs to the Wildlife Trust. This area of the reserve is a patchwork of chalk grassland and scrub, this type of diverse, herb rich habitat with lots of shelter is preferred by lots of insects, it offers lots of possibilities.

Plants like thistles and knapweeds are very good nectar sources used by lots of insects.

The scrub offers both shelter and an additional variety of flowers, bramble being very important and popular. I found the large hoverfly Volucella inflata feeding on a bramble flower.

As I was photographing it a male flew in and mating took place.

A few years ago when at Old Winchester Hill I found a rare bee-fly, the downland villa Villa cingulata , at the time it was only the second Hampshire record in recent times. It appears it has been spreading as I found several, easily five or more, egg-laying females at Kitts Grave, I am not sure if they are recorded from there before.

We saw a good range of butterflies including very recently emerged silver-washed fritillary and white admiral.

We retired home during the heat of the afternoon so I was briefly in the garden….

What’s in My Meadow Today?

One plant I was keen to establish was lady’s bedstraw, it has tiny yellow flowers unlike most of our bedstraws which have white flowers. It grows on dry chalk soils mainly but also turns up on dry sandy areas even in acid areas.

I seem to have only got one plant to establish but it is spreading to form quiet a significant patch.

Once the day started to cool we ventured down to the coast to Lepe Country Park. Years ago I established another meadow area at this site, although in this case it was from a deep ploughed cereal field, it is now a SINC (Site of Importance for Nature Conservation) for its wildflower community. Creating grasslands of real wildlife value is relatively easy and gets quick results, helping to redress the massive loss of these habitats. Planting trees is much more popular, despite the fact that it will probably take hundreds of years for them to achieve significant value for wildlife. As anyone who manages open habitat will know trees will colonise and grow quite happily without encouragement. In fact colonising trees are one of the threats to herb-rich grasslands.

However we were on the beach, looking at beach species. Stabilised sand and shingle has its own specialist plants, one of which is sea spurge.

Rather more attractive is the yellow-horned poppy.

The long pods which give this poppy its name can be seen in this shot.

It was getting late and there were lots of small moths flying about, in the end I managed to get a picture of one, it was a Pyralid moth, quite a common one found in a variety of dry habitats, called Homoeosoma sinuella.

Off the beach an adult gannet was flying about, quite a regular sight in The Solent these days.

Emperors

Another very hot day and a good one for insects, hot conditions allow them to be especially active as they do not need to spend time sitting in the sun to warm up as they would on a more normal English summer’s day. I saw my first Blashford silver-washed fritillary of the year, they are regular in small numbers, but never common on the reserve.

Later I came across a pair of brown argus, these are the start of the second generation for this species this year.

Brown argus are one of the “Blues” but one that forgot this and so is not blue. The same area of grass was also hiding several stridulating Roesel’s bush-cricket, I am quite pleased that I can still hear these as they are quiet high frequency and so one of the species that slip away as we get older. If you do get to see one the pale line around the lower edge of the pronotum is an identifying character.

However the highlight of the day was none of these fine insects. After lunch I went over to Ellingham Pound to check how the common tern chicks were doing, the answer was just fine and it looks as though all seven will be flown off very soon. It is a good place to see dragon and damselflies and one of the only regular places on the reserve for small red-eyed damselfly and a quick check found one floating on some algae. I then started to look at the dragonflies in the hope of finding a lesser emperor, as there have been quite  few in the country recently and one was reported from Ibsey Water a couple of days ago. After seeing a couple of emperor dragonfly, a distinctive male lesser emperor shot past, after many attempts I got a couple of shots, not great, but I only had a 60mm lens with me!

The mainly dark abdomen with pale blue “saddle” is what identifies it. As I waited for it to skim past again I inevitably snapped other dragonflies too, when I looked at these pictures later I think one of them shows a female lesser emperor.

The lesser emperor is a migrant from the south, it used to be regarded as very rare but is getting more common, especially in warm summers and certainly tries to breed here now. It seems it is another species that is trying to colonise thanks to warming temperatures. The Odonata (dragonflies and damselflies) seem to be especially responsive to these changes with many species spreading across Europe dramatically in the last couple of decades.

Elsewhere on the reserve there were at least three common sandpiper on Ibsley Water where there was also a juvenile little egret and, at the end of the day, 3 adult yellow-legged gull. I also found that the pair of Mediterranean gull on Long Spit had managed to fledge a single chick, or at least I could only find one. Although they have nested with us before I cannot be completely certain they have raised a chick to flying on Ibsley Water previously.

Hopefully it will cool down a bit next week and I can get some of the paths trimmed, they certainly need it! I had intended to try today but it was just too hot.

A Bit of Drizzle!

A pretty quite day at Blashford on Monday, the heavy showers kept people indoors and I can’t say I can blame them!

heavy rain!

Despite the rain there was warm sunshine in between and this brought out a good few butterflies around the Centre, including silver-washed fritillary, red admiral, comma and small tortoiseshell, but best of all there was a humming bird hawk moth.

I walked the paths to clear any fallen branches brought down by the rain and strong winds of the weekend, approaching the Ivy North hide I saw a stick across the path, then realised it was moving, it was a large grass snake.

By the time I locked up the rain had passed and looking from the Tern hide I saw this black-headed gull, it was perched on the weed mat in front of the hide. As I have mentioned before I don’t think I have ever seen so much weed on Ibsley Water, or such thick mats of it, in fact this gull was perched on weed floating in 4 metres or more of water, although it looks pretty relaxed about it!

The gulls are starting to gather on Ibsley Water now, not in the numbers they will be later in the autumn but today I saw at least four yellow-legged gull (3 juveniles and 1 first summer), a pair of great black-backed gull with a fledged juvenile in attendance, and the usual scatter of herring gull and lesser black-backed gull. The lesser black-backs included one with an almost black, rather than dark grey back, so probably a bird from Scandinavia already on the move to wintering areas on the West African coast.

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…

Phew!! What a scorcher. – now you know I’ve run out of ideas for titles!!!

In a somewhat ironic (or iconic) piece of fortune the first mini-beast of the day was a gatekeeper butterfly which buzzed me as I opened up the gate to the Tern Hide car-park.

Other butterflies are really making their presence felt – not before time, following the unusually cold ( do you remember that?) spring.  A red admiral has been floating around the Education Centre and without moving too far away it’s been possible to see both large white and small white, meadow brown, speckled wood, peacock, comma, brimstone and what was almost certainly a silver-washed fritillary scuttling through.  Many of them will have been looking for nectar sources, but the plants that always used to be cited as the ‘butterfly bush’ , buddleia , have yet to produce much in the way of flowers– possibly another effect of the cold spring.

A gentle stroll around the path between Ellingham Water and Dockens water, ostensibly to do a bit of trimming back of overhanging branches and invasive brambles, produced a few bonuses in terms of dragonflies and damselflies including a fine male emperor dragonfly, a couple of brown hawker and numerous common blue damselflies,and one beautiful demoiselle. Only a keeled skimmer stayed still long enough to have its picture taken and that was from some distance away.

A more obvious pair of megafauna graced us with a fleeting glimpse, as a female roe deer and her fawn dashed across the lichen heath.

Along the path heading south towards the Iron Age hut there are a number of broad-leaved helleborine, which are only just starting to come into flower. Disappointingly a number of them have been decapitated, probably having been nibbled by deer.  There were, however, several intact specimens, which even before fully flowering have a delightfully sweeping architectural shape.

but only one that had started to bloom.

Helleborines are in the orchid family, a fascinating group of plants with more different members than any other family of vascular plants. Genetically they are rather complicated with more DNA than many more complex plants and animals including ourselves. As a group that is currently rapidly evolving many hybrids may be formed and for this reason may present  challenges to anyone wishing to identify the species. Given my track record on plant ID, I might be foolish, but I’m pretty sure these are broad-leaved helleborine…

As it’s the time of year for interesting insects I’ll finish, as usual, with a few moths.

A Butterfly Day

I did not get out and about much today but when  I did it was evident that it was a good day for butterflies and especially for photographing them. it was warm enough for them to be active but cloudy enough that they had to stop and sunbathe whenever the sun came out. Red admirals and peacocks are the most abundant species with lots of very smart newly emerged ones about.

red admiral

The browns don’t bask with wings open as commonly as many other butterflies but even they were basking a lot today.

speckled wood

When I was having lunch I was buzzed by a silver-washed fritillary, eventually it landed on the picnic table beside me and it allowed me to get really close up.

silver-washed fritillary

The recent warmer days and nights have seen a considerable improvement in the numbers of insects to be seen with lots of dragonflies and much better moth catches as well as more butterflies.
