Polyphylla aeolus
Kelso Dunes June Beetle
Polyphylla aeolus is a sand dune specialist scarab beetle endemic to California's Kelso Dunes in the Mojave Desert. Described by La Rue in 1998, this species belongs to a genus noted for large-bodied beetles with males possessing greatly enlarged, fan-like antennae used to detect female sex pheromones. Like other Polyphylla species restricted to sand habitats, females are likely flightless and rarely encountered. The species epithet references Aeolus, the Roman king of the winds, perhaps alluding to the wind-dispersed nature of related taxa or the windy dune environment.
Polyphylla anteronivea
Saline Valley Snow-front June Beetle, Saline Valley Snow-front Scarab
Polyphylla anteronivea is a species of scarab beetle in the family Scarabaeidae, described by Hardy in 1978. It belongs to the genus Polyphylla, commonly known as lined June beetles, which are characterized by their large size and distinctive antennae. The species is known from limited observations in North America, specifically from California.
Polyphylla arguta
Polyphylla arguta is a species of lined June beetle in the family Scarabaeidae. It is native to western North America, with documented occurrences in Arizona, Colorado, Idaho, Nevada, New Mexico, Utah, and Wyoming. The species belongs to a genus whose members are typically associated with sandy habitats and are nocturnally active, attracted to lights.
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 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 donaldsoni
Donaldson's lined June beetle
Polyphylla donaldsoni is a species of scarab beetle in the family Scarabaeidae, described by Skelley in 2003. It is a member of the lined June beetle genus Polyphylla, which is most diverse in the southwestern United States. Adults are medium-sized beetles that closely resemble Polyphylla pubescens but can be distinguished by specific morphological features. The species has an extremely restricted distribution, known only from central Georgia.
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 nigra
Polyphylla nigra is a scarab beetle in the family Scarabaeidae, described by Casey in 1914. It belongs to the genus Polyphylla, commonly known as lined June beetles, which are characterized by large body size and sexually dimorphic antennae. The species is distributed in western North America and parts of Mexico. Like other members of its genus, males likely possess enlarged, fan-like antennae used 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. Like other members of this genus, P. nubila is likely associated with sandy habitats and exhibits nocturnal activity patterns.
Polyphylla pottsorum
Polyphylla pottsorum is a species of scarab beetle in the family Scarabaeidae. It is a member of the diverse genus Polyphylla, commonly known as lined June beetles, which are characterized by their large size and distinctive antennae. The species was described by Hardy in 1978.
