The chronological and geographical distributions of immature and adult orthopteroids were compared in a semi-isolated abandoned crop field in Michigan. Seven general plant associations within the 1.8-acre field were sampled by sweeping and pit-trapping, and the relative numbers of orthopteroids within each association were determined. Thirty species of orthopteroids were captured with the following distribution by families: Acrididae 16, Gryllidae 5, Conocephalidae 3, Phaneropteridae 1, Gryllacrididae 1, Tetrigidae 2, Manteidae 1, Phasmatidae, 1.
