Pselaphinae

Adranes lecontei Brendel ( Fig. 64 )

Range: Kentucky, Mississippi, New York, Pennsylvania, Tennessee. Habitat: lives in nests of Lasius spp. ants ( Hymenoptera : Formicidae ); nests have been found in beech logs in advance stages of decay.

Collection Method: sifting Lasius spp. ant nests, rarely sifting/Berlese forest litter. Biology: obligate myrmecophile on Lasius spp. ants; adults feed on fluids obtained from their adult and immature hosts; possibly feed on dead immature ants; see Park (1932a) and Akre and Hill (1973) for interesting behavioral observations of the genus. Ferro et al. (2012a): significantly higher abundance in secondary forest, indifferent to substrate or season, probably heavily influenced by their host. Present Study: significantly higher abundance in CWD3–4 and secondary forest.
