Neocoenorrhinus germanicus (Herbst, 1797)
on Rosaceae, Salix
The adult beetles feed in the spring on young leaves. Th female deposits an egg in a young shoot not far from the tip. A few centimeters below she partly severs the shoot, causing it to wilt, fold down, and ultimately drop off. The larva bores in the decaying tip, then burrows into the soil for pupation.
Univoltine; hibernation as imago in the soil.
