Agathidium spp. (female) ( Fig. 44 )

Comments. This genus was represented in this research by males of four identifiable species; however none of the males were represented by more than 10 specimens. Information provided below is about the genus. Range: throughout eastern United States and worldwide. Habitat: high humidity locations, forests, leaf litter, dead wood. Collection Method: collection and dissection of slime molds (warming a slime mold in the laboratory will cause adults to move and become visible), sifting/Berlese leaf lit- ter and dead wood, flight intercept traps, emergence chamber. Biology: winged and wingless species, strongly associated with slime molds ( Myxomycetes), Wheeler and Miller (2005) provide a list of host associations for numerous species. Ferro et al. (2012a): significantly higher abundance in leaf litter and primary forest, indifferent to season. Present Study: significantly higher abundance in primary forest.
