Arthropoda

Elattoneura tetrica, black and yellow bambootail is a damselfly species in the family Platycnemididae. It is endemic to Western Ghats in India.Teneral males look like the female in colour and markings; adult lose almost all their markings beneath pruinescence. A shy retiring insect, frequenting dark shady spots on submontane streams, usually in heavy jungle.

An elastomer is a polymer with viscoelasticity (having both viscosity and elasticity) and very weak inter-molecular forces, generally having low Young's modulus and high failure strain compared with other materials. The term, which is derived from elastic polymer, is often used interchangeably with the term rubber, although the latter is preferred when referring to vulcanisates. Each of the monomers which link to form the polymer is usually made of carbon, hydrogen, oxygen or silicon.
Polymer that displays rubber-like elasticity.

Elattoneura tetrica

Elattoneura souteri is a damselfly species in the family Platycnemididae. It is endemic to Western Ghats in India.It is found on the banks of submontane streams in Western Ghats, hiding in shaded areas beneath overhanging bamboo, cane or bushes. On flight, the whole of the head, thorax, and base of abdomen appear uniformly red and so easily distinguishable from other species in this genus.

Elastomer
An elastomer is a polymer with viscoelasticity (having both viscosity and elasticity) and very weak inter-molecular forces, generally having low Young's modulus and high failure strain compared with other materials. The term, which is derived from elastic polymer, is often used interchangeably with the term rubber, although the latter is preferred when referring to vulcanisates. Each of the monomers which link to form the polymer is usually made of carbon, hydrogen, oxygen or silicon. Elastomers are amorphous polymers existing above their glass transition temperature, so that considerable segmental motion is possible. At ambient temperatures, rubbers are thus relatively soft (E~3MPa) and deformable. Their primary uses are for seals, adhesives and molded flexible parts. Application areas for different types of rubber are manifold and cover segments as diverse as tires, shoe soles, and dampening and insulating elements. The importance of rubbers can be judged from the fact that global revenues are forecast to rise to US$56 billion in 2020.Rubber like solids with elastic properties are called elastomers. Polymer chains are held together in elastomers by weakest intermolecular forces. This weak binding forces permit the polymers to be stretched. Natural rubber, neoprene rubber, buna-s and buna-n are elastomers.
