Acrotrichis spp. ( Fig. 48 )

Range: throughout North America. Habitat: leaf litter, decaying logs, tree holes, fungi, animal dung, under bark, moist decaying organic matter. Collection Method: sifting/Berlese organic material, flight intercept trap, emergence chamber. Biology: De Coninck and Coessens (1981) studied Acrotrichis intermedia (Gillmeister) : probably general detritivore, adults live about 150 days and produce ~ 10 eggs each, probably reproduction takes place throughout the year with overlap of generations. Ferro et al. (2012a): significantly higher abundance in leaf litter, primary forest, and fall. Present Study: signifi- cantly higher abundance in CWD2 and primary forest.
