Observations on the biology of insects constitute an important source of information which is useful not only in establishing phylogenetic relationships but also in formulating methods of control for species that are economically important. Contributions to the knowledge of the bionomics of sawflies are of sporadic occurrence in the literature; but when such studies are aggregated and perused by a worker interested in the group, it is possible for him to draw conclusions which might otherwise be impossible without many years of accumulation of his own data. This paper constitutes a contribution to the knowledge of the bionomics of two species of North American sawflies with particular emphasis upon the developmental stages.
