But as a matter of fact, it really is dusk as they both belonged to the first wave of insects coming to light just after sunset. They disappeared as quickly as they came. By the way it's fascinating to see how synchronized the various species are with respect to flight timing .
I used to put up a Skinner type trap and look it up only in the morning. I now realize, having sat in front of a lighted white sheet during the night, that I was probably missing a lot of critters which don't enter the trap, manage to escape , or possibly get eaten by other captives!
Anyway, once again, your help is greatly appreciated.
