Sawfly Life History Adaptations to Woody Plants
Our aim is to examine various life history attributes of these sawflies and identify general patterns. Whenever possible, we compare sawflies to forest Lepidoptera to underscore differences and similarities between the two groups. First, we determine the degree to which herbs, shrubs, and trees are used as larval food. Then, focusing primarily on the largest group, the tree-feeding sawflies, we examine which plant parts these sawflies consume and how polyphagous they are. Next, we look at various attributes of the host trees to determine whether or not tree genera that support few sawfly species have any life history traits in common with tree genera that support many species. Then we look for patterns among sawflies that are forest pest in the Great Lakes region of North America. We conclude by examinig the conifer-feeding Diprionidae and Tenthredinidae of the Great Lakes region, comparing life history attributes of outbreak and nonoutbreak species. 1993
