Identification

Distribution

This introduced species occurs throughout Florida, achieving its highest densities in northern areas of the state. It usually occurs in disturbed areas, but seems to thrive in some pine plantations. Nests are under loose bark, or at the bases of pine trees, occasionally arboreal, or under shingles. First reported in the U.S. (Louisiana) in 1978 (Wheeler and Wheeler 1978). Note that the identity of this species and virtually all other Brachymyrmex is problematical and confirmation of the occurrence of this species in the United States needs confirmation. Pest status: occasionally enters open buildings in large numbers. No previous published Florida records; earlier specimens: 1988. (Deyrup, Davis & Cover, 2000.)

Biology

Deyrup, Davis & Cover (2000): This species seems to adapt well to open pine forests (high pine and flatwoods habitats) in north Florida, as well as to the usual open disturbed areas favored by many exotics. Huge nests may be found in the loose bark at the bases of large pine trees, a nesting site also favored by native species of Paratrechina, Pheidole, Solenopsis and Brachymyrmex. The diet of B. musculus is unknown, except that they eagerly feed on honeydew, and are therefore likely to promote the increase of sap sucking insects.
