I grew up catching them. They're cool as shit, we called them horny toads.

They're all dying out now. They eat one species of ant that is being outcompeted by fire ants which are from south america. The species of ant they eat you can recognize, they're aggressive but not as much as fire ants, lightly ants but they build small little sandy mounds usually with one hole in the middle. Their sandy usually looks like tiny clumps.
