Calosoma inquisitor

The species is found in northern Africa, Europe (northward to southern Scandinavia) and East to Asia Minor, Iran and the Caucasus, with isolated populations in eastern Siberia and Japan.

They can fly well and are found not only on the ground, but also in bushes and on trees.

In case of danger the beetle can fall and then threaten by lifting up the front body and spreading the mandibles.

The hatching larvae are also predatory and develop very quickly.

The beetles emerge in June, but still linger in a diapause until next spring in the ground.
