Haplocampa Silvestri, 1912

Haplocampa is the dominant taxon in volcanic caves of western North America, and 26 species are known from caves, primarily in the Pacific Northwest (Ferguson 2009). The majority of Haplocampa appear to be cryophiles as they are often found at high elevations and in caves with ice, and are sympatric with cryobionts such as ice crawlers ( Grylloblattodea: Grylloblattidae: Grylloblatta) (Ferguson 1983; Schoville and Graening 2013).
