I'm passing on the following from a friend who is not on BEE-L:
If you are in the Bee-L net ask if anyone has information _first hand_
on the mature beetle passing through the 7/inch wire. We know the
larvae go through very easily and most of the “professionals” just say
the beetles pass through. Does anyone really know first hand? I know
they vary in size, but I suspect the male is possibly the only one that
can pass.
