Helops attenuatus
attenuated darkling beetle
Helops attenuatus is a North American darkling beetle in the family Tenebrionidae, first described by LeConte in 1851. The species belongs to a genus characterized by elongated body forms and relatively long antennae compared to many tenebrionids. Like other members of the tribe Helopini, it exhibits morphological traits that can cause confusion with ground beetles (Carabidae), particularly in antennae structure.
Helops bachei
Helops bachei is a darkling beetle in the family Tenebrionidae, described by John Lawrence LeConte in 1861. The genus Helops contains species that can be challenging to distinguish from ground beetles (Carabidae) due to some shared morphological features. Like other Helops species, H. bachei possesses antennae with segments longer than wide, resembling the filamentous antennae of ground beetles rather than the bead-like antennae typical of many darkling beetles. However, it can be identified as a tenebrionid by its concealed mandibles. The species is native to North America.
