''Lestes viridulus'', the emerald-striped spreadwing, is a damselfly species in the family (biology), family Lestidae, the spreadwings. It is native to Bangladesh, India, and Thailand. Description and habitat It is a medium sized damselfly with brown-capped yellow eyes. Its thorax is khaki brown, paling to creamy white on the sides. The dorsum of the thorax has two very narrow metallic green stripes, running closely parallel to the mid-dorsal carina. Wings are transparent with pale brown pterostigma. Abdomen is yellowish brown on the sides with metallic-green dorsal stripes up to segment 8. Segment 9 has a dark dorsal mark on basal half.

Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica. All damselflies are predatory insects; both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, but the ...
