About Myrmecocystus testaceus Emery, 1893
Myrmecocystus testaceus Emery, 1893, commonly known as Myrmecocystus testaceus, is a species of honeypot ant. This species can be found across the entire western United States and the extreme southern region of British Columbia. Myrmecocystus testaceus is typically nocturnal, and it builds its nests in sand. This ant is able to spray formic acid from its gaster, which can break down skin tissue. Unlike ants that attack by stinging and swarming, Myrmecocystus testaceus handles its prey by stretching it by its legs. It continues this approach until the prey splits or dies from a combination of bites and applied formic acid.
