Hi John


Most likely one of the swift moths (Hepialidae) or wood/goat moths (Cossidae) - both of these families contain some very large species. A swift moth may be more likely as I think a lot of them are known to emerge and fly in autumn, particularly after rain; the big wood moths (Endoxyla spp) may be more likely in summer. The swift moth Trictena atripalpis would be my guess, females have a wingspan of up to 16cm - have a squizz at this site and see if anything looks like yours - just click on the relevant family and browse the photos – there are some nice shots of live specimens

I know this is off-topic for COG, but can anyone ID the very large moths

that were beating themselves to death against my studio window last night.

They are the size of a small bird, with a wingspan of maybe 5-6 inches,

bodies around 3 inches long and as fat as my forefinger. Generally a

mottled brown colour with rather slender wings. After leafing through my

fairly useless insect book, I think that they are perhaps a type of goat

moth. They don't have the pointed abdomen of the hawk moths and they

fold their wings back over their bodies at rest, rather than laying them

out flat to the sides.
