Golden delight

Yesterday I accompanied Bob to the old Hanson concrete plant to see how the area was developing, what was growing and what insects were around. On our way we popped in to Tern Hide where there was a common sandpiper foraging on the shore of Ibsley Water:

The old Hanson plant, now named by Bob as ‘the empty quarter’, does look rather barren. Most of the area has crushed concrete underfoot, but plants including St John’s wort, ragwort and lots of common centaury are growing, alongside grasses and the pioneer tree species silver birch, which is quick to colonise new habitats following disturbance and will need managing to ensure the saplings do not take over.

The sandy looking area in the photo above was probably the most interesting as here there was less crushed concrete and an abundance of holes in the softer ground, evidence the area is being used by solitary bees and wasps. There is obviously enough flowering on this part of the reserve and the surrounding banks for the green-eyed flower bee below:

There were lots of dowdy plume moths (identified later by Bob, who also discovered one of their favourite larval food plants is common centaury) and we also saw a species of leaf-cutter bee and a six-spot burnet moth:

I haven’t set foot on this part of the reserve before so it was nice to get the opportunity to have a look and see how it is developing. For those of you who are regular, long-standing readers of the blog, please don’t ask about the footpath, there is still no news…

Elsewhere on the reserve I have seen my first cinnabar moth caterpillars, with their distinctive black and yellow stripes. Their bright colours are a warning to predators not to eat them: as they merrily munch their way through common ragwort, the toxins present inside the plant build up inside them, making them unpalatable to predators.

There are also plenty of gatekeeper butterflies on the wing, like this one enjoying the common fleabane in the sweep meadow:

When I emptied the moth traps this morning there were a couple of nice species inside, including a yellow-tail, coronet and a canary-shouldered thorn.

The highlight from the moth trap though was a hornet. Hornets are attracted to light, but are very docile first thing in the morning, taking a while to warm up and fly off. This one was quite content walking around the bench until it was ready to fly away, and it was nice to have a really good look at it up close:

Although hornets may get a bad press, they are much less aggressive than their smaller relative the common wasp and will only sting if attacked. They play an important role in pollination and are a gardener’s friend, helping control unwanted pests with their diet of insects.

Today has been a really good day for dragonflies, with common darter, emperor and brown hawker all on the wing over the ponds by the Education Centre. The common darters in particular have been posing nicely and letting you creep up quite close for a photo:

Today’s highlight though has to be the golden ringed dragonfly a visitor spotted over the ponds behind the Centre, with regular visitor John letting me know so I could take a photo:

This striking black dragonfly has yellow rings along the length of the abdomen, hence the name, and green eyes. The females are the longest dragonfly in the UK due to their long ovipositor which can reach 84mm in length. If they choose to rest they may stay in one place for some time and although present on the reserve (we sometimes catch their nymphs in the Dockens Water when river dipping, where they prefer flowing acidic water to still water) they are not quite as easy to see here as some of our other dragonfly species. It was a rather nice end to the day!

One Day, Two Reserves

I am not often at Blashford on a Saturday, but this weekend I was, I managed to intersperse catching up on paperwork with a walk round all the hides. Getting around the reserve is very pleasant but also highlights all the tasks that need planning into the coming winter season, I think an eight month winter would just about be enough!

Opening up the hides I saw a greenshank and three wheatear from the Tern hide, which suggested that there might well be migrants about and with luck “something” might turn up.

As usual the day proper started with a look through the moth trap. This contained no rarities but one unexpected moth, a very fresh dark form coronet, this is an attractive moth and one we see quite often, but it flies in June and July. If I was to get one at this time of year, I would have expected it t be an old, battered one on its last legs, not a pristine newly emerged one.

The cumulative results of my wanderings throughout the day indicated that there were indeed a reasonable scatter of migrants around the reserve. Chiffchaff were frequently to be seen, although willow warbler were many fewer than last week. In one mixed flock of birds near the Lapwing hide I saw a very smart juvenile lesser whitethroat, a rather rare bird at Blashford these days. On the south side of the main car park a spotted flycatcher was catching insects from the small trees and there were several blackcap eating blackberries.

In the early afternoon I was in Tern hide when I spotted an osprey in the distance flying towards us down the valley, it looked as if it was going to come low over Ibsley Water, but as it came over Mockbeggar North lake a large gull started to chase it and, rather than brush off this minor irritation, it gained height and headed off at speed to the south. It was a young bird and is going to have to learn to tough out such attention.

It was not a bad day for insects, I saw red admiral, painted lady, small white and speckled wood, despite almost no sunshine and there were good numbers of migrant hawker and brown hawker about. I also saw more hornet than I had noticed so far this summer and very widely about the reserve too.

Other birds of note were mostly signs of approaching autumn, a single snipe near the Lapwing hide was the first I have seen since the spring here and later wigeon, one on Ivy Lake and 4 on Ibsley Water were also the first returns that I have seen.

For a couple of years now I have been noticing increasingly large floating mats of vegetation in the Ivy Silt Pond and kept meaning to identify the plant species involved. I finally did so yesterday and one of them, the one with the rosettes of pointed leaves, is water soldier, a rare plant in Hampshire and mostly found on the Basingstoke canal!

It is probably most likely to be here as a result of escaping from a local garden pond, but might be wild, anyway it seems to be a notable record and as far as I know it has not been recorded here before.

In the evening I went out to another reserve in my area, Hythe Spartina Marsh, it was close to high water and I was interested to see if there was a wader roost. There was, not a large one but interesting, it included 74 ringed plover, 30 dunlin, 2 turnstone, 3 grey plover and a single juvenile curlew sandpiper. In addition 2 common sandpipers came flying north up  edge and on the way across the marsh I saw a clouded yellow butterfly nectaring on the flowers of the sea aster. I also saw that on e of the juvenile ringed plover had got colour rings on its legs, however it would only ever show one leg so all I could see was a white ring above a red ring on the left leg, not enough to identify where it had come from. Ringed plover can breed locally on our beaches or have spent the summer way off in the high Arctic of Canada, so it would have been good to see all the rings.
