Abstract

The absence of males in 1000 adults examined over a 2 year period, the facility with which unmated females deposited eggs, and the high percentage (86%) of these eggs which hatched are presented as evidence for obligatory parthenogenesis in Cloeon triangulifer McDunnough. It is suggested that the unusually long (June to November) emergence period of the species is a result of parthenogenesis.
