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.
