Sclerotin
Sclerotin is produced by insects by adding a large quantity of protein to chitin. This protein is tanned by the insect. The equivalent of sclerotin in vertebrates is keratin (Wigglesworth, 1971).
The mandibles of caterpillars, which are used to gnaw on wood, are made of sclerotin. © Bernard Schmeltz
