Polyphylla erratica
Death Valley June Beetle
Polyphylla erratica, commonly known as the Death Valley June Beetle, is a scarab beetle in the subfamily Melolonthinae. It is narrowly endemic to the Amargosa River drainage basin in the southwestern United States. The species is associated with saltgrass communities and has been documented at Saratoga Springs in Death Valley. Like other Polyphylla species, it exhibits sexual dimorphism in antennal structure, with males possessing enlarged, lamellate antennae for detecting female sex pheromones.
