Adult tipulids were collected at weekly intervals in a southern New York open woodland. Sweeping, light trapping, and Malaise trapping yielded 4003 crane flies representing 125 species. The 25 most common species were identified and enumerated. The Malaise trap data were used to examine phenology, diversity, and species evenness. Further numerical analysis with the Malaise trap data indicated similarity among collecting periods. These results were used to outline the seasonal subcommunities that existed over a 2-year period.
