The Ramulus granulatus stick insect has a mustache-like front leg. It is very cute, but what is it for? If this insect is under threat from a natural predator or when it is caught, it will shed its legs to escape. Stick insect nymphs can regenerate broken legs after several molts. The re-growth of the leg appears curled during regeneration. As adults do not molt, their legs cannot regrow if they break off.
