Goat Moth Cossus cossus
The Goat Moth gets its English name from the strong 'goaty' odour of the caterpillar. The caterpillar burrows into the trunks of various deciduous trees, and feeds on the wood. Because of the long digestion period required for this food matter, the larvae often live for up to five years before pupating. Image: Paul Kitchener (Flickr).
