Appearance
Melolontha papposa looks similar to the Common cockchafer Melolontha melolontha, but among other things has a much shorter pygidium. The males have seven very long and bend "leaves" on their antennae, whereas the females have only six much shorter leaves.Behavior
The females are heavier than the males and prefer to crawl around on or even in the ground, while the males fly around and use their huge antennal leaves as sensory organs in locating the females for mating.The larvae live in the ground and are known as notorious pest in olive orchards, where they feed on the roots of the olive trees.
