title: Flight and dispersal of periodical cicadas.
abstract: Periodical cicadas (Magicicada spp.) rarely flew distances greater than 50 m across an open field or along a forest edge. Most cicadas caught after flying 50 m or more were females and all of these females had mated. Flights were most common when adults were 2 to 3 weeks old. Among insects in general, most dispersing individuals are barely post-teneral or extremely young. Cicadas are discussed as an exception to this generality. Both sexes of cicadas are attracted by the male song to chorusing centers for mating (Alexander and Moore 1958). Trees which were chorusing centers had more eggnests than those which were not, suggesting a lack of postmating dispersal from the chorusing trees.
