Ein Larve (Raupe) des Weidenbohrers - Cossus cossus

Solution: it is the larvae of Cossus cossus, a moth (lepidoptera); the larvae lives in the wood of willows. Es handelt sich hier um die Larve (Raupe) des Weidenbohrers, eines Schmetterlings, dessen Larve im Holz der Weide lebt. It has been found in firewood and be brought to me. It is probably a larvae of the beetle family “Cerambycidae“, but does anybody know which species? It size is about 6-7 cm. It has a red back. If you know more - let me know!
