Lasiorhynchites sericeus (Hbst., 1797)

The distribution of the Thief Weevil Lasiorhynchites sericeus (family Rhynchitidae) stretches over all of Europe except the north. In the east it reaches far into Russia. The 5.2 to 6.4 mm large species is known to occur throughout Germany, but everywhere only very sporadically. The beetles live from May till July on oak. They exhibit a very interesting brood parasitism: Contrary to other representatives of the genus, the female does not produce a leaf-roll herself, but places her egg in the leaf-roll of the Leaf-rolling Weevil Attelabus nitens while still "under construction". Also, the females lay their eggs in already finished rolls. The larva eats the egg of the Leaf-rolling Weevil before it consumes the leaf as the brood substrate. (KR/CB)
