Imperiled
Guides
Blabomma californicum
Blabomma californicum is a species of true spider first described by Simon in 1895. It belongs to the family Cybaeidae (previously placed in Dictynidae). The species is notable for having only six eyes rather than the typical eight eyes found in most spiders. It occurs in western North America across Canada, the United States, and Mexico, and is listed as imperiled in Canada.
Cicindela waynei
Bruneau Dune Tiger Beetle, Bruneau Tiger Beetle
Cicindela waynei is a rare, range-restricted tiger beetle endemic to sand dune habitats in southwestern Idaho. It belongs to the C. maritima species group, a clade of sand-dune specialists in central and western North America. The species is classified as globally imperiled by state and federal land management agencies due to its small population size and vulnerability to habitat degradation. It was first described in 2001 and remains one of the most geographically constrained tiger beetles in North America.
Cotinis aliena
Keys green June beetle
Cotinis aliena, commonly known as the Keys green June beetle, is a critically imperiled scarab beetle endemic to extreme southern Florida. The species has not been observed since 1998 and is known from only four localities: three in the Florida Keys and one in southern peninsular Florida. Its extreme rarity and apparent extirpation risk make it one of North America's most endangered beetle species.
Hesperapis oraria
Gulf Coast solitary bee, Gulf Coast evening bee
Hesperapis oraria is a rare, solitary bee endemic to the northern Gulf Coast of the United States. Described in 1997, it is the only known member of the subfamily Dasypodainae in eastern North America. The species is monolectic, relying exclusively on the coastal plain honeycomb head (Balduina angustifolia) for pollen and nectar. It is critically imperiled due to its restricted range and habitat specificity.
Nomotettix cristatus
crested pygmy grasshopper, crested grouse locust, northern crested grouse locust
Nomotettix cristatus is a small pygmy grasshopper in the family Tetrigidae, commonly known as the crested pygmy grasshopper or crested grouse locust. It is one of approximately 35 Nearctic species of Tetrigidae. The species exhibits three recognized subspecies with distinct geographic distributions across North America. Like other members of its family, it is characterized by an elongated pronotum that extends over the abdomen, a trait distinguishing pygmy grasshoppers from typical grasshoppers in Acrididae.
