Nylanderia pubens

Nylanderia pubens is a species of ant of the genus Nylanderia, commonly called the Caribbean crazy ant. It was originally described as Paratrechina pubens from Saint Vincent, Lesser Antilles. This species was moved from Paratrechina to the genus Nylanderia in 2010.

These ants are about one-eighth inch long and are covered with reddish-brown hairs. The colonies have multiple queens. An infestation of this species, or a related species named Nylanderia fulva, is ongoing in and around Houston, Texas.
