The species is endemic to sand dune habitats in the Warner Valley of Utah. Like other members of the genus Polyphylla, it exhibits sexual dimorphism in antennal structure, with males possessing enlarged, lamellate antennae used to detect female sex pheromones. The species is rarely encountered and poorly documented in scientific literature.
Polyphylla comes
High Mountain June Beetle
Polyphylla comes is a large scarab beetle in the family Scarabaeidae, commonly known as the High Mountain June Beetle. It belongs to a genus noted for males with enlarged, fan-like antennae used to detect female sex pheromones. The species occurs in the southeastern United States. Like other Polyphylla species, it is primarily nocturnal and attracted to lights.
Polyphylla crinita
Long-haired June Beetle
Polyphylla crinita, commonly known as the Long-haired June Beetle, is a large scarab beetle in the family Scarabaeidae. It is distinguished from closely related species by the presence of setae (hair) on the pronotum. The species occurs in western North America, with records from California north to British Columbia and east to Wyoming, as well as in Baja California, Mexico. Like other members of the genus Polyphylla, males are attracted to lights at night and possess enlarged, fan-like antennae used to detect female sex pheromones.
Polyphylla decemlineata
Ten-lined June Beetle, Watermelon Beetle
Polyphylla decemlineata is a large scarab beetle native to western North America, commonly known as the Ten-lined June Beetle or Watermelon Beetle. Adults are notable for their distinctive ten white stripes on dark elytra and greatly enlarged, fan-like antennae in males. The species is strongly attracted to lights and exhibits distinctive pheromone-mediated mating behavior where males actively search for flightless females. Larvae develop underground, feeding on roots of grasses and other plants.
Polyphylla diffracta
diffracted lined June beetle
Polyphylla diffracta is a species of scarab beetle in the family Scarabaeidae, commonly known as a lined June beetle. It belongs to a genus characterized by large, robust beetles with distinctive fan-like antennae in males. The species occurs in arid and semi-arid regions of the southwestern United States and northern Mexico. Like other Polyphylla species, males are attracted to lights at night and use their enlarged, lamellate antennae to detect female sex pheromones.
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.
Polyphylla mescalerensis
Polyphylla mescalerensis is a species of scarab beetle described by Young in 1988. It belongs to the genus Polyphylla, commonly known as lined June beetles, which are characterized by large body size, fan-like antennae in males, and strong attraction to lights. The species is known from sand dune habitats in southeastern New Mexico and adjacent areas, where it was first collected at Mescalero Sand Dunes. Like other Polyphylla species, males likely use their enlarged antennae to detect female sex pheromones.
Polyphylla nubila
Atascadero June beetle
Polyphylla nubila, the Atascadero June beetle, is a species of scarab beetle in the family Scarabaeidae. It is native to North America, with distribution records indicating presence in California, USA. The species belongs to the genus Polyphylla, a group commonly known as lined June beetles or ten-lined June beetles, characterized by males with enlarged, fan-like antennae used to detect female sex pheromones.
