Both are long-dead and partly decomposed - with interesting results fo any student of insect wing structure who might have had their attention caught by the membranes in the Peacock's damaged wing. It looks like a wartime aircraft returned from a mission with flak damage - an image which is sadly germane to the goings-on in today's wider world.
The Small Elephant Hawk is the second I've found dead this year. The Peacock is a much more common discovery, along with Small Tortoiseshells and occasionally Red Admirals, in nooks or behind furniture where dusters seldom venture. Be careful with these butterflies, though; many are not dead but sleeping, to emerge when the days get warm again.
My leisurely pace of blogging at the moment belies my intense activity on the page - reached by clicking of the tab above - called 364 and counting - my records. I am listing all the moths which have visited me both in Leeds and here in Oxfordshire, with photos. I hope it may be a useful aid to others engaged in this absorbing hobby when sorting IDs for the insects they find. I've just reached the end of moths beginning with C tonight. Excelsior!
