Specimen Labels

Parasitic species living in mixed nests with the larger Strumigenys loriae (Wilson & Brown 1956). Workers exploit coccids inside the nest for honeydew.

Identification

A member of the Strumigenys mutica-group. See notes under Strumigenys mutica. See Wilson and Brown 1956. The type material was collected in a rainforest.

Biology

Wilson & Brown (1956) - this parasitic species is incapable of capturing prey, this task being done by their hosts Strumigenys loriae. Workers were observed exploiting Pseudococcidae that affix themselves onto roots in nest chambers. One colony in a large rotting moss-covered log lying on the ground consisted of 1170 workers, 4 dealate queens, 84 alate queens and 51 males. Its host colony numbered 1622 workers and 16 dealate queens. Host and parasite pupae were mixed together in several chambers. Dealate queens and workers of both species were distributed amicably throughout the nest. Trophallaxis was observed between adults.
