Re Devid Martin's photos, 1: small white (the large white has much blacker markings and is ... larger); 2 marbled white (I think. Not familiar with this species) 3 - red admiral; 4 - peacock; 5 - no idea, but it isn't a comma. The ragged edges of its wings have been caused by damage, not design. 5 - clouded yellow, I think. One source I checked said it is mostly confined to the south, but another said it can be found all over the UK, mostly close to the coasts. My guess is that with climate change, all bets are off with regard to migratory species like this.
