Anochetus mayri

Brown (1978): Anochetus mayri is found mostly in forests under stones, in moss on rocks or logs, in rotten twigs on the forest floor, or in larger bodies of rotten wood. The workers and queen feign death, and are difficult to see.

Distribution
This taxon was described from Antilles Is.

It is also found in the United States (southern Florida), Central America (Mexico, Guatemala, Honduras, Costa Rica), the West Indies (Dominican Republic, Saint Lucia, Barbados, Grenada) and northern South America (Ecuador, Brazil, Venezuela, French Guiana, Guyana).

Biology
This widely distributed species is found in leaf litter where it is a predator of smaller arthropods. Collection of this species in Florida was detailed by Deyrup (2002). Individuals were found to be common in deep litter at the base of pines and oaks in an environmental teaching facility in West Palm Beach Co. The ant was not a dominant species (in terms of abundance), and was not neither aggressive nor strongly defensive.
