Diploperlini
springflies
Diploperlini is a tribe of springflies (Plecoptera) in the family Perlodidae, established by Stark & Szczytko in 1984. The tribe comprises approximately 13 genera and more than 30 described species. Members of this tribe are aquatic insects in the nymphal stage and terrestrial as adults.
Helopicus
springflies
Helopicus is a genus of springflies (order Plecoptera) in the family Perlodidae, established by Ricker in 1952. The genus contains at least four described species distributed across eastern North America and parts of Asia. Species in this genus are part of the stonefly group Systellognatha, characterized by their predatory or omnivorous feeding habits as nymphs.
Isogenoides
springflies
Isogenoides is a genus of springflies (family Perlodidae) comprising eight described species distributed across North America. These stoneflies inhabit cool, lotic freshwater systems and exhibit species-specific vibrational communication through drumming. The genus demonstrates considerable life history diversity, including extended diapause periods and semivoltine development in some populations.
Skwala
springflies
Skwala is a genus of springflies (Plecoptera: Perlodidae) established by Ricker in 1943, containing approximately five described species distributed across North America and Asia. Species in this genus are amphibiotic, with aquatic nymphal stages in freshwater streams and terrestrial adults. At least one species, Skwala pusilla, has been documented as predatory. The genus has been subject to cytogenetic study, with Skwala compacta representing the first photographic documentation of stonefly chromosomes.
