Abstract
The sexual behaviors of Okanagana canadensis (Provancher) and O. rimosa (Say) are described. In northern Michigan, O. canadensis is typically found in coniferous vegetation, such as cedars; whereas O. rimosa frequent deciduous vegetation. In both species, males call from stationary perches, and females approach them. Females have no specialized receptivity signals, but both males and females engage in bouts of wing flicking that may be alternative, low-risk signaling. Mating is brief and involves no elaborate courtship. The Okanagana mating system, characterized by male advertisement and female searching, is contrasted with that of Magicicada spp., the periodical cicadas of North America, and discussed in the context of relative risks of signaling and searching behaviors.
