Ant nest beetle secretions on their antennae and body allow them to interact with ant workers. It is believed that the beetles use an acoustic mechanism to successfully imitate the sounds of an ant queen thus permitting them access to the nest without alarming the ants. The defensive bombardier behaviour is never used against ants. Males of some species are attracted to lights during some parts of the season and are thought to disperse from one ant nest to another. Males are thought to be short-lived. These beetles feed on ant eggs, larvae and adults by piercing their mandibles into the abdomen or
Erratic ant nest structure to concentrate solar heat onto the ants' brood. Nuptial flights take place in June, although they may be postponed during colder years to July. Erratic ant The erratic ant ("Tapinoma erraticum") is a species of dolichoderine ant first described in 1789 by Latreille.
