Soliperla sierra
Soliperla sierra is a stonefly species in the family Peltoperlidae, first described by Stark in 1983. The species is notable for its vibrational communication system, with male call and response signals described for the first time in a 2023 study. Males produce repeated monophasic call signals consisting of one to six signals with inconsistent inter-call intervals. Females respond with sequenced monophasic answers that do not follow all male calls, and occasional three-way exchanges occur when males respond to female answers. The species is known from California.
