Biology

Strumigenys form small nests in soil, under or between rocks, or in and under logs or under cattle dung. Some species nest in association with other ants such as Bothriomyrmex mayri or Rhytidoponera metallica. Although they are normally slow moving, they can run quickly when disturbed.^{[citation needed]}

Strumigenys xenos is a permanent social parasite, which forms no workers and lives in the nests of its host S. perplexa.^[2]

Most species specialize in the hunt of springtails, and the others eat other soft-bodied arthropods.^[3]

Distribution

Despite having many species occurring in temperate ecosystems, the genus is most diverse in the tropical rainforests around the world.^[4] In those regions, Strumigenys is often an abundant component of the litter community.^[5]

In terms of regional diversity, the known fauna of Strumigenys is distributed as follow: 139 species are known from the Afrotropical region, 60 from the Australasian region, 258 from the Indo-Australian region, 94 from the Malagasy region, 59 from the Nearctic region, 214 from the Neotropical region, 97 from the Oriental region, and 81 from the Palaearctic region.^[6]
