Tile-horned Prionus
Prionus imbricornis is a large longhorned beetle in the subfamily Prioninae, commonly known as the Tile-horned Prionus. Males are attracted to synthetic 3,5-dimethyldodecanoic acid, a compound originally identified as a female-produced sex pheromone in the related species P. californicus. The species belongs to the subgenus Neopolyarthron and is one of several Prionus species in eastern North America.
