description Goat moth Overview
The goat moth (Cossus cossus) is a large species of wood-boring moth native to Europe and parts of Asia. It is most identifiable during its larval stage, where the caterpillars live inside the trunks of deciduous trees, feeding on wood for up to four years before pupating. These larvae emit a distinctive, pungent odor said to resemble the smell of a male goat, which serves as a chemical defense mechanism. The adult moths are heavy-bodied and feature mottled grey and brown patterned wings that provide camouflage against tree bark.
help Goat moth FAQ
Why is the Goat Moth given such an unusual name?
The Goat Moth gets its name from the strong, distinctive odor produced by its caterpillars. This scent is famously said to resemble the smell of a male billy goat.
Where do Goat Moth caterpillars live and feed?
Unlike most moth caterpillars that feed on leaves, Goat Moth caterpillars bore directly into the solid wood of living tree trunks. They spend several years tunneling inside the wood before they are ready to pupate.
Is the Goat Moth harmful to forests and trees?
Yes, the extensive boring behavior of the caterpillars can cause significant structural damage to deciduous trees like willows, oaks, and poplars. The tunnels they create leave the tree highly vulnerable to fungal infections and rot.
How large do Goat Moths get?
The adult Goat Moth is a large, heavy-bodied European species with a substantial wingspan. Despite their impressive size, the adult moths have muted grey and brown wing patterns that allow them to camouflage perfectly against tree bark.
