Anisoptera - Dragonflies
Dragonflies are insects in the sub-order Anisoptera (meaning "unequal-winged").
Hind wings are usually shorter and broader than forewings.
They are usually large, strongly flying insects that can often be found flying well away from water.
When at rest, they hold their wings out from the body, often at right angles
to it.
The eyes are very large and usually touch, at least at a point.
The gallery pages give a brief description followed
by observed behaviour patterns, a flight chart, where to
see and a link to a photo gallery. With the wealth of
identification information available through books,
websites etc I've concentrated on species behaviour
patterns to further aid identification in the field,
along with some choice examples experienced over the
years. |
