I was out and about collecting leaf miner pupae this morning in N.Dean before the rains set in. The ones on oak and Beech are really easy to find at the moment so I've got quite a few pupae overwintering in my garden at the moment ready to bring inside in a couple of months.
One pupa I didn't expect to find was what I think is that of a Green-veined White butterfly. It's attached to a Sycamore on the towpath near Copley - you can just make out the silk girdle round it's middle. I'd be interested to hear what others think, maybe it's just a well marked Small White? I'll go back and collect it soon and try and rear it through just to be 100%.
