Stauropus fagi

Lobster moth

Description

The lobster moth Stauropus fagi is a moth species found across Europe to Japan, mainly inhabiting deciduous forests, including beech and riparian forests, as well as woodland edges. The moth is nocturnal, attracted to light, and camouflages on tree trunks during the day. It lays relatively large brown eggs on host tree leaves, and the larvae feed on deciduous trees such as Fagus, Quercus, and Prunus. The caterpillar has an ant-like or mantis-like appearance and sprays formic acid when disturbed. It pupates shallowly in the ground, overwintering as a pupa.
