This study was performed to determine the ability of a green roof to create a suitable habitat for invertebrate species. Insects were collected from the roof of Smithdeal Hall at Virginia Wesleyan College, Norfolk, VA. Sampling used different techniques to sample both flying and ground dwelling invertebrates. Invertebrates were identified to the lowest taxonomic unit possible. Fall 2007 sampling included 21 different morphospecies, including 9 dipteran taxa and 4 coleopteran taxa. Hemiptera, diptera, and coleoptera were the most abundant, with 13-29 individuals collected from each of these groups. The data collected for this study demonstrated the ability of a green roof to facilitate invertebrate colonization by standing as a fairly effective mimic of the surrounding natural area and a replacement of impermeable, concrete surface roofs.
