Formica Integra (Hymnoptera: Formicidae) 1. Habitat, Nest Construction, Polygyny, and Biometry
Abstract
Formica integra Nylander was studied during late May 1972 in its native habitat: an oak-hickory forest on a ridge in the Lower Piedmont, west-central Georgia. Sexual and worker broods were present in subterranean portions of the numerous, closely-spaced nests which were typically associated with rotting oak logs. Functional polygyny was demonstrated by the presence of numerous wingless, subterranean females (with sperm and mature eggs) per nest. The number of ovarioles per ovary, worker body measurements, and (size-dependent) worker pigmentation patterns were similar to those published for polygynous European species of the F. rufa group, especially Formica polyctena Foerst. from Germany.Downloads
