Neodiprion taedae
Neodiprion taedae is a conifer sawfly species in the family Diprionidae, described by Ross in 1955. Like other members of the genus Neodiprion, it is a folivorous herbivore whose larvae feed on pine needles. The species is part of a diverse assemblage of conifer sawflies in eastern North America, where outbreaks can cause significant defoliation of pine forests. It is one of approximately 25 Neodiprion species documented in eastern U.S. forests.
Zadiprion townsendi
bull pine sawfly
Zadiprion townsendi, commonly known as the bull pine sawfly, is a species of conifer sawfly in the family Diprionidae (Hymenoptera). The genus Zadiprion is a small group of sawflies whose larvae feed on pine needles. This species is associated with bull pine (Pinus ponderosa), serving as a defoliator of this economically important timber species. Like other diprionid sawflies, Z. townsendi undergoes complete metamorphosis with larval stages that feed gregariously on host foliage.
