Grand Teton National Park Report
Cyphoderris strepitans, is a primitive orthopteran which survives only in the mountains of Wyoming and Colorado (Morris and Gwynne 1978). The males rub their forewings together to produce a calling song. This stridulation is presumed to function, as in other acoustic Orthoptera, in attracting conspecific fema1es for mating and in maintaining a broadcast territory around each singer.
