I thought this might be helpful for some people who might be having trouble definitively sexing their blue death-feigning beetles. I hope the photos are decent enough for the difference to be visible. These are two of my beetles, and if you have a bunch you can usually sex by size alone - I got a pair on the first try just by looking for a small male and a big female. But if you only have a few or they're all similar in size, this is the definitive way to tell.

Males have small hairs on their antennae, extending out and down, away from the antenna. Females have a few small hairs as well, but not nearly as many and they are very close to the antennae itself, not aimed out and down. They're visible to the naked eye although a magnifying glass or a bright light may be helpful to see them.

It's probably the one I posted on with that info. :) I got a question about it via PM as well so I thought perhaps the photo would be useful to someone.

I know this post is old and im taking a shot in the dark, but do you know if the same gender identification applies to cryptoglossa variolosa as well? I got one recently and I am having trouble identifying the gender of it.
