Sunny Day

As is usual on a sunny day in August the reserve was very quiet yesterday, the birds having finished nesting and most of the migrants have yet to get moving. The human visitor too mostly go elsewhere when the summer sun comes out. However the sun does bring out the insects and there was a fair showing of dragonflies and butterflies, although tempered by the fact that numbers seem to be well down this summer across the board.

The moth trap catch was quite good, but much lower than I would have hoped, but with a warm week ahead we could be in for bumper catches by next Sunday morning when I have a moth event. To whet the appetite here are a couple of pictures of regulars from the trap.

Out on the reserve there were insects about but numbers are still rather disappointing, I did see a painted lady though, a species that has not been common this year. On the edge of the lichen heath I was looking for bee wolves when I spotted what, at first I thought was a large ant, but in fact was a true-bug nymph that was trying to look like an ant.

If anything they look even more convincing from the side.

You can see the rostrum, that is the piercing feeding tube under the head that gives it away as a true bug, rather than the jaws that an ant would have.

One group of insects that do seem to be abundant are the grasshoppers. One species that still seems to be increasing is the lesser marsh grasshopper, a previously coastal species that has spread inland.

Although there were few birds of note around, there were significant numbers of some species. On Ibsley Water I counted 271 tufted duck and 355 greylag geese, the goose flock included what looked like an emperor goose accompanied by a barnacle goose and  a single hybrid off-spring.
