My new ground beetles!!

I got 4 new Callisthenes simplex from DETHCHEEZ on the beetle forum. They arrived today and they are munching away on some Eleodes hispilabris larva. I think there is at least 1 female, and 2 males, but one of them I can't really tell what sex it is. I am keeping them in a smallish container for right now, I am gonna get them a bigger cage today. Anyway, here are some pictures!

I am gonna try really hard to breed these, they are pretty cool little beetles! I was handling one and it sprayed defensive fluid into my eye, which stung quite a bit. However there seems to be no lasting damage, and now I know not to handle them too close to the face, LOL! Anyway, that's it for today, I hope you guys enjoyed! :)
