First described: By the French entomologist Pierre André Latreille in 1802 as Formica longicornis.
Paratrechina longicornis is no slow walker. This ant's name "crazy" stems from its erratic and rapid movement. It has the ability to successfully survive in highly disturbed and artificial areas, including ships at sea. Since it can live indoors with humans, it can exist at any latitude. This ant has been reported from as far north as Sweden and Estonia, and as far south as New Zealand (where it is not, however, established). It is considered a pest, nesting in apartments and other buildings, as well among others in trash, refuse, plant and tree cavities, and rotten wood. In houses nests are built in walls, narrow spaces, house plants, and empty containers. Colonies tend to be small to moderately sized, including as many as 2,000 workers and 40 queens. The colonies are highly mobile and relocate when conditions become unfavorable to these insects. See also: Species of previous months
