Polyphylla
Lined June Beetles
Polyphylla is a genus of scarab beetles in the family Scarabaeidae, subfamily Melolonthinae, containing approximately 50–85 species distributed across North America, Central America, southern and central Europe, northern Africa, and southern Asia. The genus is commonly known as "lined June beetles" due to the distinctive white elytral scales that form longitudinal stripes on most species. Adults are nocturnal and strongly attracted to lights, while larvae are root-feeders with extended development periods.
