Abstract

Great Burnet, Sanguisorba officinalis L. (Rosaceae), is the previously unknown larval host plant of the sawfly Empria testaceipes (Konow, 1896) (Tenthredinidae: Allantinae). We report here that young, endophagous larvae inhabit galls in the leaves, while later instars are external feeders on leaves. This is the first report of a gall-inducing habit in the subfamily Allantinae. The galls of E. testaceipes on S. officinalis and the larvae are described and illustrated, and the distribution of this rarely recorded sawfly is summarised.
