Prionus spinipennis
Prionus spinipennis is a large long-horned beetle (Cerambycidae: Prioninae) endemic to sand dune habitats of southeastern New Mexico and western Texas. It is one of two Prionus species specialized to this ecosystem, with P. arenarius occupying spring and early summer, while P. spinipennis occurs in late summer and fall. Males are attracted to prionic acid lures, a synthetic analog of female sex pheromones. The species was described by Hovore & Turnbow in 1984.
