Abstract

Voltinism in Microvelia hinei was studied in southern Illinois during 1989 and 1990. This species apparently overwintered as adults, which became active in late April; adults were last collected in late September. First instars were found from mid-May to late June, second instars from early-May to late October, third instars from mid-May to mid-July, fourth instars from mid-May to mid-August, and fifth instars from mid-May to mid-August. The sequences of peaks of nymphal instars and adults indicate that this species is at least bivoltine in southern Illinois. This species was reared from egg to adult at 26.7 ± 0.6°C and under a 14L:10D photoperiod. The incubation period averaged 6.41 days; and the five nymphal stadia, 4.28, 2.76, 2.52, 3.00, and 4.08 days, respectively. Total developmental time averaged 25.00 days.
