The standard blunder trap and “bat proof” trap. (a) The standard blunder trap ~70 mm × 90 mm typically used to capture the most of the insects discussed in this paper (b) The plastic “bat proof” trap which has a sticky cardboard replaceable insert. When closed the entry gap that is less than 15 mm prevents bats from coming into contact with the sticky surface. Photographs by permission of Robert Child.
