Abstract

Nematus spiraeae Zaddach, a European sawfly that feeds on Aruncus diocus (Walter) Fernald (Rosaceae), was discovered in Quebec. This probable introduction is the first report of N. spiraeae in North America and the first record of a sawfly feeding on Aruncus in North America. A diagnosis and some life history notes are given for N. spiraeae.
