Strumigenys

Species of Strumigenys can be difficult to find other than when encountered in leaf litter. They form small nests in soil, under or between rocks and in rotten wood. They are normally slow moving but can run quickly when disturbed. Most are specialist predators on Collembola while others will take a range of small soft-bodied arthropods. They are occasionally found at honey baits. They can be locally common while being absent from similar areas nearby. One species, S. xenos, is a permanent social parasite. That is, it occurs only as queens with no workers and is always found in the nests of its host, S. perplexa. Other species have been found nesting in association with other ants, including Pachycondyla mayri and Rhytidoponera metallica in Australia.
