Busy in the Sunshine

Sorry for the lack of posts, we seem to have been very busy and by the end of the day exhaustion has taken over. It is the time of year when there is lots of growth to cut back, bramble regrowth to cut off and nettle to remove from potential grassland areas. Today I spent the morning removing ragwort from one of the areas due to be mowed later this month and the afternoon mowing bramble regrowth from a bank beside Ibsley Water where we are trying to establish grassland. Hot and heavy work, there are times when I think I am getting too old for it! Being out in the sun did mean I saw lots of butterflies, meadow brown and gatekeeper are probably the most abundant now.

There are also a number of summer broods out, I saw peacock, small tortoiseshell, common blue, brown argus and small copper. Possibly a side effect of the hot weather is the number of common blue that are unusually small, some as small or smaller than brown argus. I think this happens because the food quality of the plant the caterpillar was on was not good enough or in sufficient quantity for it to grow to full size.

When I had lunch I took a look at the Centre pond and there were dozens of pairs of azure damselfly pairs, egg-laying in tandem. They do this so that the male can be sure that the eggs being laid are the ones that he has fertilised. Some dragonflies do the same and others will stay hovering close tot eh female whilst she lays.

I know that I was only doing “What’s in My Meadow Today” during 30 Days Wild, but I will end with a picture from there anyway. One thing that is very noticeable as the grass has gone brown and then yellow is that some plants remain green, field scabious is one of these, which is not just green but flowering well.

30 Days Wild – Day 21 – The Longest Day

The longest Thursday in fact and so Blashford volunteers day. We were clearing bramble regrowth to help with grassland restoration around Ellingham Lake, on the way we went around Ellingham Pound where there was a redshank, a species I had never seen there before, all the ones I have seen previously on the reserve have been beside Ibsley Water. The single pair of common tern on the raft on the Pound are still present, I suspect they have small chicks, but we could not see them.

I was supposed to be doing an insect based wildlife walk int he afternoon, but there were no takers, which was a shame as there were lots of insects out and about today. The sunny weather is very popular with Odonata, dragonflies are very evident and there are lots of black-tailed skimmer basking along the paths.

As I was not doing the walk I went path cutting on the northern part of the reserve instead, on the way I passed a large flowering patch of bramble. Bramble flower is often good for feeding insects and it did not disappoint, there was a very fresh and fine white admiral, a new species for me at Blashford. Unfortunately I did not have a camera with me so you will just have to imagine it! Whilst path cutting I also saw my first ringlet of the year, although I know the butterfly surveying volunteers have been seeing them for  a few days now.

At the end of the day going to lock up I noticed a patch of hart’s tongue fern in a patch of sunlight, they are typically in shady places and I would guess this patch is only in full sunlight for a very short time each day and perhaps only in mid-summer.

Back home in the evening I had the moth trap to look at as I had not had time to go through it in the morning. There was nothing of great note until I found a small elephant hawk-moth, not rare but a favourite of mine.

Finally………..

What’s in My Meadow Today?

As summer moves on  anew range of plants are starting to flower and yesterday the first field scabious flower started opening. They will go on flowering well into the autumn and are very popular with bees, hoverflies and butterflies as well as looking great in the grass.

I established the original few plants from seed and planted them out as small plants, these have now grown very large and are producing seedlings of their own.

30 Days Wild – Day 14 – Concrete to Orchids

Blashford’s brilliant volunteers were working hard again, this time on a project to produce a grassland on the former concrete block plant entrance. This is a project with a lot of difficulties, the site was abandoned fro three years and much of it got overgrown with bramble. The old hard standings and buildings were broken up leaving a mix of rubble, gavel and a very little soil. This might sound a bad start for a grassland, but it actually has potential, the most diverse grassland habitats are those with very poor soils and this area has a very, very poor soil. From this poor beginning we are making real progress, the old tarmac entrance now has flowering ox-eye daisy and bird’s-foot-trefoil and this is in just the second season since seeding. Perhaps most remarkably as we headed back for a cup of tea we found a flowering bee orchid!

I suspect it may have come not as a seed but as a small plant along when some of the soil was being moved around, but clearly it is doing well. When I returned in the afternoon to do some more mowing of bramble regrowth I came across a pyramidal orchid on the bank that used to edge the road. The soil there was not so disturbed, so I would guess it had arrived some time ago.

Although the day had started drizzly it dried up, as it always does on a Thursday morning, famously it never rains during our Thursday volunteer sessions, whatever the forecast might say.

By afternoon it was hot in the sunshine and as I ate lunch I saw lots of insects. On bramble flower behind the Education Centre I found a yellow-and-black longhorn beetle.

I also saw several dark bush cricket nymphs.

What’s in My Meadow Today?

The wild carrot that I featured before the flowers open a while back is now in full flower and attracting insects.

There are several species of dronefly, all named for their similarity to male honey-bees. I think this one is Eristalis pertinax, but actually might be E. nemorum as it looks a little bright to be pertinax.

The reason for my late post of this time is that I was out again last night surveying nightjar. I heard possibly one that moved about or up to three, unfortunately I could never hear two at the same time, so I cannot say with certainty that there was more than one.

A Day Unparalleled

Although I failed to see it a when I opened up this morning, the grey phalarope remained on Ibsley Water as did a juvenile black tern and the two ruff. A feature of recent days on this lake has been the mass fishing events, when a flock of cormorant, sometimes a hundred or more will act together to drive  large shoal of small fish into a corner. This attracts grey heron, little egret and the great white egret, which patrol the shallows, everyone gets some fish, sometimes several, which shows just how big the shoal must be.

The swallow and martin flock was perhaps a little smaller today, but still ran to several thousand and once again included a single swift. However it was not the birds that made for an “Unparalleled” day, it was a moth, a Clifden nonpareil, or blue underwing.

These are very large and, until recently, very rare moths. Having become extinct in the UK they turned up only as rare migrants until recolonizing about ten years ago. The New Forest area seems to be their stronghold now and in the last few years we have seen one or two each year, but they at still a real treat. It is just a shame it did not turn up yesterday for the moth event.

We have been doing quite a lot of grass cutting recently, some areas we are managing like meadows to increase the variety of wild flowers and this means we have to cut and remove the bulk of the grass by the end of the growing season. Today we cut areas of the sweep meadow used by education groups near the Ivy North hide. In this areas we cut in alternate years to leave longer herbage for over-wintering insects. If we leave it uncut for too long bramble and small trees start to colonise and many of the grassland plants, upon which so many insects depend, disappear.

The grass is raked up and piled into a heap which should provide a good place for grass snakes to breed next year, especially if the heap is in a sunny spot.

Mouldy Old Day

On my way to open up the hides this morning I found another slime mould on a log near the Woodland hide. More regular readers will perhaps know I am rather fond of these bizarre organisms. This morning’s species was the coral slime mould Ceratiomyxa fruticulosa and it resembled a hoar frost in colour and shape.

I spent the day working with the volunteers continuing to develop the new area of grassland beside the path through the old concrete works. Before anyone asks, no I don’t have an opening date for the path yet, but I hope it will be reasonably soon. We were doing some cutting, but also a lot or raking up and it was remarkable how many young common toad there were in the area, certainly many tens and probably hundreds, clearly it is an important area for them. The seeding we did back in the spring has worked surprisingly well considering how dry it was, although it seems to be making up for that now. There are lots of young bird’s foot trefoil and ox-eye daisy plants coming up so it should look pretty good in a year or two.

At the end of the day I set off to lock up the hides and my eye was caught by something brilliant yellow, another slime mould! This time troll butter, it is almost dayglow in brightness.

It was only when I downloaded the picture that I noticed the tiny beetle.

 

 

On the Hop

On Tuesday we were working on the western shore of Ibsley Water again with the volunteers. Over the years we have been controlling ragwort and nettle that used to be the dominant here to convert it to grassland, at last we are seeing some real results. Much of it is now mainly grass with a good range of herb species, especially bird’s-foot trefoil. We are also seeing a lot more butterflies and other insects, marbled white are especially frequent in the grass there now.

As we worked I heard a lot of Roesel’s bush-cricket and saw field grasshopper and meadow grasshopper. The grassy sward is not ideal for all species though, the mottled grasshopper likes grassland with lots of bare ground and very dry conditions, at Blashford they are mostly found on the lichen heath.

One distinctive thing about the males of this species is that the ends of the antennae are bent out and swollen, they are also our smallest grasshopper. The males were chirruping, or more correctly stridulating, the object of this is to attract a female and I found one that was evidently playing the right song.

The females are quite a bit larger and have more conventional grasshopper antennae.

30 Days Wild – Day 22: Punctuated

It was thankfully cooler today which allowed us to do some work along the open western shore of Ibsley Water. As it was Thursday the “us” was the famous Blashford volunteer team. We were trimming brambles and pulling ragwort. I know ragwort is a great nectar source, but in this case we are trying to establish grassland where there has been bramble, willow and nettlebeds, this means mowing, but as we have ponies on site we need to remove the ragwort first. Ponies will rarely eat growing ragwort, but if cut and mixed in grass they will and so can get poisoned.

This shore was dominated by huge beds of ragwort and nettles but years of cutting and light grazing are taking effect and we now have mostly grassland with patches of ox-eye daisy, bird’s foot trefoil and other more desirable species. In turn this is attracting insects such as long-winged conehead.

IMG_1898

We saw a good few butterflies including good numbers of comma. It seems they are having a very good year and the fresh summer brood emerging now is particularly strong. This generation will breed and produce another generation of adult in the autumn which will them hibernate.

IMG_1916

comma

They get their name from the white comma-shaped marking on the under-wing, which is not visible in this shot. Their ragged wing outline makes them less butterfly-shaped and so harder for predators to find, this is especially so when the wings are closed.

I ran two moth traps last night, only about 50m apart, but one under trees and the other in the open. An illustration of what a difference location makes is seen from the number of hawk-moths caught. The one in the open contained 8 elephant hawk-moth, a pine hawk-moth and 2 poplar hawk-moth, whereas the one under the trees contained just one eyed hawk-moth.

As you will have gathered from this blog, I am a fan of insects in general, even horseflies, although I am less keen on them when they come into the office as this one did today.

It is the females that bite, so it would be better if this one went outside again.

 

30 Days Wild – Day 15: Trying to Impress

I was out on the eastern side of Ibsley Water with the volunteers this morning to clear the areas we cut and which are grazed by ponies of ragwort. It is toxic to animals, but they will usually not eat when it is growing, however they will if it is cut and gets mixed with grass or hay. At one time it was one of the commonest plants in this area but now it is much reduced and overall the grassland is looking much better, with quite a good range of species. A couple of highlights this morning were several patches of corky-fruited water-dropwort.

IMG_1455

corky-fruited water-dropwort

Corky-fruited water-dropwort is an Umbellifer, one of the carrot family and is very attractive to insects, this one had lots of pollen beetles on it. It is quiet frequent in unimproved grasslands in a swathe roughly south of the M4, so it is pleasing to see it at Blashford where the grassland is still recovering from the ravages of mineral extraction. Another find was knotted clover, a plant of dry sandy places, often near the coast, I am not sure if I have found it at Blashford previously.

At lunchtime I tried the pheromone lures for clearwing moths again, completely without success. However I did spot a handsome black-and-yellow longhorn beetle.

After doing various odd jobs in the afternoon I went to lock up the hides and found a pair of crab spiders on a hemlock water-dropwort flower head, The male is quite different from the female and a lot smaller so he has to tread carefully if he is not going to get eaten.

It seemed it was not only the spiders that were making plans, on a nearby ox-eye daisy I saw a female hoverfly Eristalis horticola, with a male hovering low over her and darting from side to side. I am not sure if she was impressed but he was trying hard to dazzle her with his advanced hovering skills.

I also found another slime mould, on the same log as the one the other day, although this was clearly a different species.

The only new bird sighting of note today was of a first summer little gull as I locked Tern hide. It was pleasing to see that the single oystercatcher chick from gull island has fledged and that the remaining one near Tern hide is close to doing so. In additions the single large lapwing chick is also close to flying and two of the smaller ones are still going strong. Even better was a sighting of two well grown little ringed plover chicks today. On Ivy Lake the common tern chicks are growing well and most broods seem to still be of three chicks.

30 Days Wild – Day 13: Gulls get Rings

Tuesday is one of our two regular volunteer days at Blashford Lakes, this week’s main task was further work to improve the grassland habitat along the western shore of Ibsley Water. We have had a long-term project to remove bramble, nettle and willow that has been threatening to take dominate. This shore was remodelled into a steep bank using the topsoil removed from the gravel pit surface when it was first dug, conditions ideal for the development of nettle beds and bramble thickets. To reverse this we have been mowing to allow grass and perennial herb species to get the upper-hand.  This has been targeted work aiming to take out only the least desirable species. Even the nettle beds have elements that we leave, such as any patches with nets of peacock and small tortoiseshell larvae.

Alongside the nutrient-rich soils there are poorer patches and these have a more interesting flora including a number of bee orchid.

At the end of the day I went out to Gull Island in Ibsley Water with the bird-ringers to colour-ring a sample of the black-headed gull chicks. We have been doing this for a number of years to find out where the birds from this recently established colony go to and if the chicks reared here return to breed in later years. We managed to catch and ring thirty chicks during our short visit, a good sample.

In the evening I came across a female stag beetle on the fence in the garden, the first female I have seen this year. The day ended on a fine calm note and so I decided to head out to listen to the nightjar again. One came and perched on a branch very close by and gave great views. I never tire of watching and listening to nightjar and to have the opportunity to do so just a few minutes walk from home is wonderful.

30 Days Wild – Day 8: Flowers in the Rain

Thursday is volunteer day at Blashford and it is well known that it does not rain when the Thursday volunteers are working, but today something went wrong and we got wet! We were continuing with our project to create a diverse new grassland along what used to be the entrance to the old concrete plant, we have spread seed and cleared brambles. Now we are going back to continue with cutting back the bramble regrowth and discourage nettles and some of the denser stands of creeping thistle.

A lot of the seed we spread has germinated but is has a lot that was already there lying dormant in the seedbank. This includes some with famously long-lived seed like poppies.

Poppies used to be a common “weed” of agricultural crops but these days are effectively controlled in most by herbicides. Another such agricultural weed was field pansy, which has also appeared.

Several species of thistles have grown up too, alongside the creeping and spear thistle there are a few musk thistle, not yet flowering, but the symmetry of their flower buds appealed to me.

We also have a good showing of mullein plants with both dark mullein and great mullein, a few with mullein moth caterpillar on them. Both species have tall spires of yellow flowers, however the individual flowers are very attractive on their own.

I have high hopes for this area, it has many of the attributes you need for a herb rich grassland, a mostly poor, thin soil and a sunny aspect, if we can establish a tight sward it could become a real asset for to the reserve, good for plants, insects and close to the path and so easy to see.

My last shot of the day is also of a flower but in this case it is what was sitting upon it that was the main attraction. The flower is an ox-eye daisy and on it is a male red-eyed damselfly, I find this a difficult species to get a picture of, as they usually spend their time sitting on floating pond weed well out in the water, so one away from water was too good to miss.

This is what we should now call the large red-eyed damselfly, rather than the smaller newcomer to these shores, the small red-eyed damselfly, which tends to fly later in the season.

Although I did get wet, it was not cold and being out in a bit of weather from time to time has its own appeal, albeit in moderation. Let’s hope for a bit better tomorrow.
