Abstract: Restoration ecologists are increasingly turning to the development of models to predict how species move from a regional species pool into a restored community. Two untested assumptions of these models, however, are that ecologists have an understanding for which traits are predictors of species distribution and that such traits predictably interact to determine the community membership. The goals of this study were to sample the regional species pool of Lepidoptera and to determine whether combinations of species traits predispose species toward becoming members of the actual species pool within restored prairies. In 2004, we sampled 259 moth species from 13 Tallgrass prairie remnants and restorations in central Iowa. Species most frequently filtered from the regional species pool into prairies were those that: (1) had long flight periods and were multivoltine (2) displayed a feeding preference for legumes but not the Asteraceae or other forb families, and (3) were regionally abundant but relatively small in body size.
