Cornuplura
Pinto Cicadas
Cornuplura is a genus of cicadas in the family Cicadidae, established by Davis in 1944. The genus contains at least three described species: C. curvispinosa, C. nigroalbata, and C. rudis. Members are known as "Pinto Cicadas." The genus is part of the tribe Tacuini within the subfamily Cicadinae.
Icosium tomentosum
Icosium tomentosum is a longhorn beetle and the sole species in the monotypic genus Icosium. Native to the Mediterranean region, it has been introduced to California. The species is notable for its larval acoustic behavior: larvae produce audible sounds through mandible scraping against bark and exhibit chorusing behavior, responding to vibrations from other larvae in nearby branches.
Palmacorixa buenoi
Palmacorixa buenoi is a species of water boatman (family Corixidae) described by Abbott in 1913. It is an aquatic heteropteran known for producing acoustic signals, with diel periodicity patterns that differ substantially from those observed in related genera. Most aquatic heteropterans show increased acoustic activity in early evening, but P. buenoi exhibits atypical patterns in song type periodicity. The species occurs in North America, particularly in the Nearctic region excluding the Western Cordillera and Beringia.
Tropisternus columbianus
water scavenger beetle
Tropisternus columbianus is a water scavenger beetle in the family Hydrophilidae. It is known to produce sound through stridulation, a behavior studied in western Oregon populations alongside congeneric species. The species occurs across western North America and has been recorded in aquatic and semi-aquatic habitats.
Tropisternus lateralis limbalis
Tropisternus lateralis limbalis is a subspecies of water scavenger beetle in the family Hydrophilidae. It is known to produce acoustic signals, with males generating sounds that function in mate attraction and courtship. The subspecies has been documented in western Oregon and has a broad distribution across North America extending into South America and the Caribbean.
