Gilpinia frutetorum
Nursery Pine Sawfly
Gilpinia frutetorum is a European conifer sawfly in the Diprionidae family, belonging to the G. socia species group. The species was first described by Fabricius in 1793. Ovipositor morphology has been described and illustrated in recent taxonomic work comparing European and Japanese Gilpinia species.
Neodiprion
Neodiprion is a genus of conifer sawflies in the family Diprionidae, containing approximately 25 species native to North America. Larvae are specialized folivores of pine needles, with most species exhibiting strong host associations with particular Pinus species. Several species, including N. lecontei and N. sertifer, are significant forest pests capable of causing extensive defoliation during outbreak years. The genus is distinguished from related sawflies by morphological and ecological traits associated with conifer specialization.
Neodiprion abbotii
Neodiprion abbotii is a conifer sawfly species in the family Diprionidae. As a member of the Diprioninae subfamily, it belongs to a group of primitive Hymenoptera that are among the few folivores capable of feeding on conifer needles. Adults are small, stingless wasps with a saw-like ovipositor used to insert eggs into conifer foliage. Larvae are caterpillar-like but possess more pairs of prolegs than Lepidoptera larvae and lack crochets.
Neodiprion compar
redheaded pine sawfly
Neodiprion compar is a conifer sawfly in the family Diprionidae, commonly known as the redheaded pine sawfly. The species is native to eastern North America and feeds primarily on pine needles. Larvae are gregarious and can cause significant defoliation during outbreaks, though populations are typically moderated by natural enemies. The species is one of approximately 25 conifer sawfly species found in eastern U.S. forests.
Neodiprion hetricki
Neodiprion hetricki is a species of conifer sawfly in the family Diprionidae, described by Ross in 1955. Like other members of the genus Neodiprion, it is a folivore specialized on conifer needles. The species is part of a diverse sawfly fauna in eastern North America that includes at least 25 conifer-feeding species. Specific biological details for N. hetricki remain poorly documented compared to better-studied congeners such as N. lecontei.
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.
