Derobrachus leechi
Derobrachus leechi is a large prionine longhorn beetle described in 1977 from the southwestern United States and Mexico. It belongs to a genus commonly known as palo verde root borers, though specific host associations for this species remain undocumented. The species is rarely encountered in collections and field observations are sparse.
Prionus arenarius
sandwalker prionid
Prionus arenarius is a species of longhorned beetle in the family Cerambycidae, first described by Hovore in 1981. It belongs to the subfamily Prioninae, a group of large, robust beetles commonly known as prionids or sawyers. The species is associated with sandy habitats, as suggested by its specific epithet "arenarius" (Latin for "of sand"). Field observations indicate it is attracted to prionic acid pheromone lures, with males being strong fliers active at dusk and early night, while females are rarely encountered and appear to be flightless.
Prionus debilis
Prionus debilis is a long-horned beetle in the family Cerambycidae, occurring in the tallgrass prairies of the eastern Great Plains. Males possess hypersegmented, flabellate antennae adapted for detecting female sex pheromones. The species was first documented to be attracted to prionic acid lures in 2015, representing a significant finding for the genus. It is considered uncommonly collected and appears to have a relatively restricted distribution compared to other Prionus species.
