Bugs, bugs, and more bugs

Two weeks ago was the awesome bug fair at the Natural History Museum of LA, which is always a great event to attend. I was looking forward to it this year because we were planning on getting some companions for our gray death-feigning beetle, Stumpy. In preparation for this, we upgraded her tank to a 10 gallon terrarium and got her fresh plants.

She started laying eggs in the new enclosure, which I took as a sign of approval. However, I have suspected that the eggs that she has been laying may not be fertile, so we were really hoping to get a male for her. When Bug Fair rolled around we picked up 3 more beetles. We think we did get a male, as the smallest beetle likes to clamp on top of the identified females (ran up to stumpy first thing) and they always try run away.

One of the other beetles is most likely another female, as she exhibited egg-laying behaviour fairly soon after being placed in the tank. Hopefully, we'll have little ones in a few months, although I am worried about getting this larger tank up to the temperature that I suspect may be necessary for larval development (over 100 degrees F).

Here you see the ovipositor...

and lay those eggs, lady!

WOW! congrats. I wonder what it is about your setup that encourages egg laying where it's been so seldom observed. I hope you continue to take notes, there may be a paper in this!
