(1991-05-01 - 1993-11-01) Describe the composition and abundance of canopy dwelling insects. Survey insects to establish site specific data on species abundance and diversity, and to establish permanent monitoring sites for long term trend information. Document insect biodiversity with respect to elevation and habitat. Document taxonomic diverstiy and abundance of selected insect groups, especially Lepidopters, Diptera, Hymenoptera, and Coleoptera. Conduct a light trap survey for macrolepidoptera at three sites on Mount Mansfield where collections were made between 1990-1995.
