Description

Damselfly (suborder Zygoptera), any of a group of predatory, aerial insects that are in the order Odonata . Damselflies are found mainly near shallow, freshwater habitats and are graceful fliers with slender bodies and long, filmy, net-veined wings. Damselflies are generally smaller, more delicate, and fly weakly in comparison with dragonflies (suborder Anisoptera). Their colours can be stunningly vivid. Wingspans among the 2,600 damselfly species range from 18 mm (0.71 inch) to about 19 cm (7.5 inches) in Megaloprepus caerulatus, a giant damselfly of tropical Central and South America.
Damselflies can usually be distinguished from dragonflies by their thinner, needlelike abdomens and by the way they hold their wings when at rest. With few exceptions, damselflies hold their wings vertically and together, rather than horizontally and spread apart. Also, the four wings are almost identical in size and shape and in the vein patterns. The large eyes of damselflies differ from those of dragonflies in that they are always widely separated, rather than close together or touching each other.
