Prionus fissicornis
Prionus fissicornis is a long-horned beetle in the family Cerambycidae, distinguished as the sole member of the monotypic subgenus Prionus (Antennalia). It inhabits shortgrass prairie habitats in the Great Plains of North America. Adults are highly attracted to prionic acid lures, and emergence appears to be triggered by rainfall events. Unlike some congeners, adults do not appear to construct or occupy burrows.
