Here is a cool Trap jaw ant, Orectognathus. These are Dacetine ants, known from Australia and Southeast Asia. They typically nest is soil. One of our recent visitors in the lab, Marc Seid, found and collected a colony of these ants with their brood and a queen from Murramarang National Park, NSW. Strangely enough, the workers did not feed on collembolans that I provided them, but only fed on maple syrup.
