During the last decade 14 species of sawflies that attack conifers have been abundant, at least locally for one or more years, in the northeastern United States. Some of these species, 6 of which are of foreign origin, have increased in importance as pests in recent years, and considerable damage has been caused in some localities, more especially in young plantations of red, Scotch, and jack pine and spruce. This paper gives a key for the identification of the large larvae of the more important species and a brief resumé of the life history and general habits of the species, together with information on their food plants, the damage they have caused, and methods of control.
