Cicindela decemnotata
Badlands Tiger Beetle
Cicindela decemnotata, commonly known as the badlands tiger beetle, is a flashy tiger beetle species in the family Carabidae. It is the westernmost representative of a species group characterized by green coloration with variable red markings on the head, pronotum, and elytra. The species has undergone recent and rapid phylogenetic radiation following glacial recession, with five recognized subspecies based on morphological and molecular evidence. Populations show relatively low genetic divergence despite marked morphological differences, suggesting colonization within the past 10,000 years.
Haplocampa
two-pronged bristletails
Haplocampa is a genus of two-pronged bristletails (Diplura: Campodeidae) established by Silvestri in 1912. The genus contains at least five described species, including four named by Silvestri in 1912 and 1933, and one described in 2019 from Vancouver Island, Canada. Species in this genus exhibit varying degrees of cave adaptation, with some showing only slight morphological modification for subterranean life. The genus demonstrates biogeographic connections across the North Pacific, with close affinities to Pacificampa (Japan/Korea), Metriocampa (Siberia), and Eumesocampa (North America), suggesting historical dispersal via the Bering Land Bridge.
