Anoxia villosa is a beetle from the family of scarab beetles (Scarabaeidae). The beetles are similar to the cockchafer native to Central Europe, but only occur in some areas in Germany in the Rhine plain between Kehl and Darmstadt. They were to be found very frequently in the region around Hockenheim in 2003 and 2007.
features
The beetles are 23 to 29 millimeters long. The wing and pronotum are light brown to reddish brown in color and very lightly haired. The space between the pronotum and the wing covers is densely overgrown with light hair.
Occurrence
The animals are found in southern Europe and Asia Minor , but they repeatedly penetrate into Central Europe.
Way of life
The larvae ( grubs ) develop in sandy soil for three years and feed mainly on grass roots. They overwinter as a pupa in their fourth year , the adults hatch in June to August of the following year. Similar to the cockchafer, they fly at dusk and settle on the treetops where mating takes place. The females bury themselves in the ground again after dark; the males stay in the trees. Depending on the weather, the animals fly for several days in a row.
Since the beetles occur only locally in Central Europe and are only active at dusk, they do not cause any significant damage to agriculture or forestry. In more southern countries, especially in Spain, they can occur in large numbers, similar to the cockchafer in Central Europe and cause damage mainly to fruit trees and vines.
