Resilin is an elastomeric protein found in many insects. The protein was first discovered by Oda in the locust wing-hinge. As of 2005 it is the most efficient elastic protein known (Elvin et al., 2005). The elastic efficiency of the resilin isolated from locust tendon has been reported to be 97 % (only 3 % of stored energy is lost as heat). It has no regular structure but its randomly coiled chains are crosslinked by di- and tri-tyrosine links at the right spacing to confer the elasticity needed to propel some jumping insects distances up to 150 times their length (as found in fleas). Resilin must last for the lifetime of adult insects and must therefore operate for hundreds of millions of extension and contraction; its elastic efficiency ensures performance over the insect's lifetime. Resilin exhibits unusual elastomeric behaviour only when swollen in polar solvents such as water.
