Oh, to Bee in England…

As though to emphasise the change in season today was one of those rare days when it was possible to see both brambling and swift at Blashford Lakes an opportunity that lasts for only a few days.  When I started birdwatching in the Midlands our equivalent was seeing fieldfare and swallow in the same place, on the same day. The brambling were at least 2 males at the feeders and the swift at least 14 over Ibsley Water.

Despite the remaining reminders of winter it felt very spring-like, with orange-tip, green-veined and small white, comma, peacock, brimstone, holly blue and several speckled wood butterflies seen, along with the year’s first damselfly, the large red.

After last night’s thunder storm I was not surprised that the moth trap was not over-filled with moths, although the catch did include a lesser swallow prominent, a pale prominent and a scarce prominent, the last a new reserve record, I think.

The warm weather has encouraged a lot of insects out, I saw my first dark bush cricket nymph of the year near the Centre pond. Nearby I also saw my first dotted bee-fly, this species used to be quite scarce but can now be seen widely around the reserve, although it is well outnumbered by the commoner dark-bordered bee-fly.

The wild daffodil are now well and truly over but the bluebell are just coming out.

A lot of trees are in flower now or are shortly to be, the large elm on the way to Tern hide is still covered in flower though.

Trees are a valuable source of food for a lot of insects and the find of the day was a species that makes good use of tree pollen. I had spotted what I at first thought were some nesting ashy mining bees Andrena cineraria, but they did not look right. That species has a dark band over the thorax and black leg hairs. This one had white hairs on the back legs and no dark thorax band. I took some pictures and it turns out to be grey-backed mining bee Andrena vaga, until very recently a very rare species in the UK which seems to now be colonising new areas.

They make tunnelled nests in dry soil and provision them with pollen from willows for the larvae.

The same area of ground also had several other mining bees, including the perhaps the most frequent early spring species, the yellow-legged mining bee.

Back to some birds

I have been off for the week and today was my first day back. In my absence the reserve has turned green! Many of the trees have leaves bursting through and around the lakes emergent plants are doing what they do best and emerging.

The change of seasons is very apparent, with Ibsley Water having swallow, sand martin and a few house martin swooping over at least 47 wigeon and a goldeneye, reminders of winter. A fine adult little gull was hunting insects over the lake in the morning, but seemed to have gone in the afternoon. The rain of early afternoon brought in a flock of 25 Arctic tern, always a treat and at the end of the day some of them had joined the 4 common tern on the shingle near Tern hide giving a great comparison.

Migrants generally are still rather few apart from chiffchaff and blackcap, which are both around the reserve in good numbers. Today I found just singles of willow warbler and reed warbler, we usually have just one pair of willow warbler but there should be many more reed warbler to come.

Other more random sightings I had today included a red kite, a pair of mandarin duck, 4 goosander and 3 snipe. I also had reports of 2 white wagtail and a common sandpiper.
