Ceuthophilinae
cave crickets, camel crickets, spider crickets
Ceuthophilinae is a subfamily of Rhaphidophoridae comprising North American cave crickets. Members exhibit morphological adaptations to subterranean life including reduced eyes and depigmentation. They serve as hosts for parasitic larval mites in the group Parasitengona. The subfamily includes genera such as Ceuthophilus and Hadenoecus.
Gammarus fasciatus
Gammarus fasciatus is a freshwater amphipod native to North America. Laboratory studies demonstrate that food type significantly influences growth rates, with algae and animal matter supporting greater growth than detritus-based diets. The species serves as a host for the acephaline gregarine parasite Ganymedes oaklandi. In the Great Lakes region, populations have declined due to competition with the invasive Ponto-Caspian amphipod Echinogammarus ischnus.
