The 6 to 7 mm large Hazel pot beetle Cryptocephalus coryli (family Chrysomelidae) belongs to the larger representatives of the approx. 50 species of the genus in Germany. Its distribution ranges from Spain over Central Europe and Russia to Siberia till Korea. The stenotopic, thermophilic species prefers warm slopes and sun-exposed edges of forests. It develops mainly in hazel (Corylus) and birch (Betula). After egg deposition, the females cover the eggs with their own dung and drop them into the leaf litter underneath the bush. After hatching, the larvae continue to add to the pot from their own droppings. When threatened, the larvae retreat into the pot and also hibernate in the pot. In Germany, Cryptocephalus coryli is recorded from most Federal States, but is regarded as vulnerable (RL 3). (CB)
