Observation of Anoxia villosa near Hockenheim
|
 |
On June 25th, 2009, hundreds of specimens of the scarabaeid beetle Anoxia villosa were observed swarming at dawn near Hockenheim. In Germany the species occurs in the sandy areas of the Rhine river plains. In the Mediterranean countries Anoxia plays a role similar to the cockchafer (Melolontha sp.) in Central Europe. In Germany, Anoxia swarms approx. 4 weeks after Melolontha, and essentially at the same time like the June bug (Amphimallon sp.), but is much bigger than Amphimallon and strongly resembles Melolontha, except the pubescent lower side and the 4–/5–membered lamellate antenna. In Germany Anoxia is classified as vulnerable (RL 3).
