Interpretive Summary: The caterpillar-like larvae of sawflies can cause considerable economic damage in forests. Some outbreaks in coniferous forests cover thousands of acres and result in growth reduction and tree death. Eight species in two genera feed on the needles of lodgepole and ponderosa pines in western United States. This leaflet gives the hosts, distribution, description, and life history and habits of each species. The information provided will benefit and be of use to state and federal foresters or anyone encountering sawfly damage on these pines.
Technical Abstract: Eight species of Diprionidae feed on lodgepole pine (Pinus contorta) and ponderosa pine (P. ponderosa) in western United States: Neodiprion burkei Middleton, N. annulus contortae Ross, N. autumnalis Smith, N. fulviceps (Cresson), N. gillettei (Rohwer), N. mundus Rohwer, N. ventralis Ross, and Zadiprion townsendi (Cockerell). The recognition, damage, distribution, and life history of each species are discussed.
