Research output: Contribution to journalArticlepeer-review


Voltinism in Neogerris hesione was studied in southern Illinois during 1989 and 1990. This species apparently overwintered as eggs, which hatched during late April and early May. First and second instars were found from late April through late September, third instars from early May through late September, fourth instars from mid-May through late September, fifth instars from mid-May through the third week of September, and adults from late May through early November. The sequences of peaks for instars and adults strongly indicates that this species is trivoltine in southern Illinois.
