and this moth article:
"According to Penn State College of Agricultural Sciences, Papaipema nebris is native to North America and produces one generation per year. In its adult stage it's a moth that lays its eggs singly or in groups some time in September and October in dead leaves of grasses and weeds. The eggs overwinter and begin to hatch around mid–May through mid–June. Its larval stage lasts between nine and 12 weeks."
