Newly-hatched preying mantis - isn't he cute!?

So our lab ordered some mantids from Home Depot (which don’t seem to be available so I presume it’s a seasonal product) for predation experiments. I was under the impression that they needed specific conditions to hatch that wouldn’t be met until next June. Then someone noticed one crawling over a desk. Sure enough, there were a few dozen wandering aimlessly about, migrating away from the egg case that was sitting in a corner of the lab. I think we got most of them, but those that we didn’t catch should take care of our fruitfly problem!
