Dragonfly
The 2,500 dragonfly species (Anisoptera) are characterized by long
bodies with two narrow pairs of intricately veined, membranous wings
that, while generally transparent, may have coloured markings. Unlike
damselflies, the front and rear wing pairs are shaped differently. In
addition, dragonflies rest with their wings spread horizontally, rather
than held vertically against each other (with the exception of one very
small family, Epiophlebiidae). Dragonflies have a more powerful build
and are generally much stronger fliers than damselflies. Dragonflies
have huge, bulging eyes that occupy most of the head, giving some a
field of vision approaching 360 degrees.
