I ventured up to the top this morning (sun was shining)!! that's a rarity.
I managed to find 8 Herald Moths in Bare Head Tunnel - but they took some finding. Nothing else of note in there where I found 6 on 11th November with 9 for Andy on 22nd/23rd Nov.
They don't seem to pose very well, and it's not easy getting a decent photo in there ! but they are still very nice to see.
