Polyphylla
Polyphylla is a genus of scarab beetle includes more than 80 species distributed in North and Central America, southern and central Europe, northern Africa, and southern Asia—from Asia Minor to Japan. They typically reside in forests and orchards with most being identified by white elytra scales forming stripes. The adult beetles are often attracted to lights. Polyphylla lay their eggs on soil near plants from where the larvae hatch and burrow down to the roots on which they will feed. They reach maturity in two to three years.
