I have a pair of blue death feigning beetles that I got a few months ago. The female is often wandering the enclosure, but the male is extremely reclusive. I don't think I've spotted him out in the open more than three times. Is this difference in behavior between the two sexes typical of this species?

Not that I've noticed. Might have something to do more with the individual than the sexes.

Sorry to intrude, but how do you sex bdf's? I've had three for the past year, but I don't know which ones are male or female. I know I've got one female, because I found a couple of eggs last year.

Males are generally smaller than the females, and males also have tiny hairs on their antennae. Here are pics of mine for comparison.

I don't think it has anything to do with a difference in sex, as males are generally more active than females (while they are of course looking for them) but I bet an age difference would make a beetle less active, as these beetles live a very long time, or as aspen said, different individuals do act differently.
