The 3rd brood for the Wall Brown started this year on the 24th August, the earliest start of this brood that I am aware of in Sussex.
I noticed at the start of this week that some were already looking past their best so I decided to walk my 4 mile survey circuit to do a count. In past years I have only done a 3rd brood count once, but with it being a perfect day (at least when I started the count), I was confident that I would see quite a few butterflies.
Along the top of the valley I saw good numbers and it was looking very good for an excellent count. As I reached the furthest point however, the cloud built up and many butterflies went to ground and it wasn't until I was almost at the end of the circuit that the sun came back out and the butterflies woke up. Despite this I still counted 51 Wall Brown on the circuit, all but 3 of them were males. One female was an absolute beauty and she also, unusually for this species, allowed a few photos to be taken of her. Not sitting on a nice background, but this is what this species often rests on.
