life history of Glyphopsyche irrorata (Trichoptera, Limnephilidae): a caddisfly that overwinters as an adult

Glyphopsyche irrorata has adapted to live in ponds with fluctuating water levels and ponds exhibiting winter drought by passing the winter as an adult in the terrestrial environment. Larvae, which hatch in May and pupate in late August, are detritivorous shredders. Males and females emerge in Septem...

Zusammenfassung:	Glyphopsyche irrorata has adapted to live in ponds with fluctuating water levels and ponds exhibiting winter drought by passing the winter as an adult in the terrestrial environment. Larvae, which hatch in May and pupate in late August, are detritivorous shredders. Males and females emerge in September, with a sex ratio of one and commence mating in the autumn. The entire population has mated by May at which time females oviposit in the water. Adult males and females are present in equal numbers in the spring and have similar longevities approaching a maximum of 8 to 9 months.
