Bionomic Notes. This species was collected from drift material (mostly grass litter) on upper margin of a sea beach, in leaf litter at base of a tree in a red oak and maple forest, in leaf litter in the crotch of a silver maple with multiple trunks in early April (this was probably an overwintering site) and among moist leaves on the margin of a vernal pool in a hardwood forest. Two individuals were collected with an aerial net late in the afternoon (15:00–18:00 h) when snow was still present in shaded areas in the forest. In Quebec, A. graminicola was collected from leaf litter beside a stream and in Salix litter at two localities in the Yukon Territory ( Gusarov 2003). Adults were collected in April, May and June. Collection method: sifting, some collected during evening flight.
