In the ladybug beetle Coccinella septempunctata, it has been shown that the spatulate tips of adhesive setae have a high concentration of the protein resilin
, which may be important to resist abrasion, and for optimizing contact zone and stability (Peisker et al.
is an arthropods protein with elastic and highly stretchable structure.
Samples of wing cord length were measured from the basal sclerite and resilin
patch of the left forewing attachment to the thorax in a straight line to the apex of the wing (Fig.
1976), whereas the center of the inner ligament is composed of abductin, a protein with properties similar to those of elastin and resilin
(Alexander 1966, Kelly & Rice 1967).

Yellow jacket wings have a dot of rubbery material called resilin
toward the wing tip along the leading edge.
Set up with the intention to serve increasing demand in the region for speciality elastomers such as thermoplastics, protein resilin
and polysulfide rubber, the plant is expected to produce approximately 110,000 tons of rubber per year, (using licensed ExxonMobil technology).
The 19 JVs are: Cloro Vinilos del Zulia, Monomeros Colombo Venezolanos, Nitroven, Olefinas del Zulia, Oxidor, Plastilago, Polilago, Resilin
, Pralca, Produsal, Produven, Propilven, Quemica Venoco, Metor, Supermetanol, Super Octanos, Tripoliven and Consortium Propilenos de Falcon (Profalca), and FertiNitro-I which went on stream in 2000.
Moreover, many other silk-like biomaterials such as elastin, collagen, byssus, resilin
, and other repetitive proteins have similar features to spider silk protein.
The proximal section is similar in extensibility to other rubber-like proteins such as resilin
and elastin, but is an order of magnitude higher in strength and stiffness.
The October issue of Nature reports that scientists in Australia have produced a near-perfect rubber from resilin
, the elastic protein which gives fleas their jumping ability and bees the ability to flap their wings 500 million times in a life cycle.
