A mountain of exposed fire ants, mounded up on the brood pile to conserve moisture.
Okay, last fire ant post for a while . (Next I’ll do things that live with ants!) Here’s a video I put together a little while back showing some of my lab work with fire ants. In particular, you can see the drip floatation technique, which I discussed in my last post, as well as the set up for an experiment on arboreal foraging behavior (climbing), and just a little bit of an experiment that involved using a fluorescent dye to track how collected food is fed to the brood.
