Copper Underwing - differences !

A good few Copper Underwing to the trap in recent weeks with a max of  9 at any one time. I always log these as Copper Underwing agg as the differences are, I find, pretty tricky to differentiate between the two similar species. Even more difficult to check live moths !!

In the local church tower last week I found some recently dead ones so selected the best two and decided it might be worth checking the underside of the underwings to see if this was, as advised, the best way of separating the two species. I think I was just lucky as the two I looked at were different.
