Cryptopygus
Cryptopygus is a genus of springtails (Collembola: Isotomidae) with a cosmopolitan distribution spanning polar, temperate, and tropical regions. The genus includes Antarctic endemics such as C. terranovus, a relict species that survived the Last Glacial Maximum on the Antarctic continent, as well as species from seashores, littoral zones, and terrestrial habitats. At least 29 species are recognized in the Americas. Some species exhibit specialized ecological associations, including an undescribed Mexican species found in association with the hermit crab Coenobita clypeatus.
Geophilus flavus
Boreal Yellow-headed Soil Centipede
Geophilus flavus is a soil centipede in the family Geophilidae, commonly found in terrestrial habitats including seashore locations across Europe. As a member of the Geophilomorpha, it belongs to a group of elongate, multi-legged centipedes adapted for burrowing in soil and leaf litter. The species is distinguished by its yellowish head and preference for moist coastal environments.
Heterocheila
half-bridge flies
Heterocheila is a genus of acalyptrate flies comprising the monotypic family Heterocheilidae. The genus contains two described species: Heterocheila buccata (Palearctic distribution across North America and Eurasia) and Heterocheila hannai (restricted to the northeastern USA and Pacific Northwest coasts). These flies are specialized inhabitants of temperate seashores, where adults and larvae feed on stranded kelp in the wrack zone.
