Dialytellus tragicus (Schmidt) ( Fig. 27 )

Range: southeastern Canada and northeastern United States, south to North Carolina and Tennessee. Habitat: found near deer dung in forested habitats and leaf litter, rarely in CWD5. Collection Method: sifting/Berlese leaf litter and rotten wood, presumably this species could also be collected with deer dung baited traps. Biology: feeds on deer and sheep dung in shaded locations, cold adapted species, generally active in winter. Present Study: significantly higher abundance in leaf litter, primary forests, and spring.
