Most often found in spring and fall, when near-surface temperatures are close to their thermal preferendum
Apparently, the preferred food is geophilimorph centipedes, which they effectively subdue, not withstanding the gluey defensive secrietions of these much larger and squirmy arthropods (Trager, pers. observation). But, other elongate, "wiggly" prey such as other centipedes and elaterid larvae, are also taken. Prey is grasped with the ants' toothy mouthparts, underground in narrow burrows, and then stung with the formidable aculeus, which is nearly as long as the entire gaster when exserted.
Mating flights occur during the cool months, September to April throughout their broad range, but obviousl, not in winter in cooler regions.
This genus and some Prionoplta are part of an ancient lineage of ants, long included in Ponerinae, but now separated into their own subfamily.
