Dragonfly and Damselfly Identification Help

Have you spotted a Dragonfly or Damselfly and need help to identify it? 

The following tips should help you to identify most species.


This page does not currently include most vagrant and migratory species. For these species visit our species profile pages.

For a more comprehensive guide to Dragonfly identification please check out the range of fantastic Dragonfly guide books avaliable via our shop.


Is it a Dragonfly or a Damselfly?

These are general differences between the two groups.


Dragonfly  (suborder = Anisoptera)

Robust body

Wings open at rest

Front wings and back wings different in shape

Eyes touching at top of the head (there are some exceptions)

Flight strong and purposeful

Damselfly  (suborder = Zygoptera)

Thin, delicate body

Wings closed at rest (there are some exceptions)

Both pairs of wings are the same shape

Eyes not touching at top of head

Flight weak and fluttering

Hawkers and Similar Species

Darters, Chasers and Skimmers


Generally dark with bright spots or stripes. Some mostly brown. Can be brightly coloured with a thick black mid-line stripe. Never with dark wing marks other than the wingspots (rectangular marks at the tip). Generally large, robust but thin bodied.

Generally with a blue, red, yellow or brown body or a combination of some of these colours. Sometimes with black markings. Some with additional dark marks on the wings. Generally smaller and stout bodied.

Almost entirely emerald green coloured, usually metallic. Often bright green eyes. Sometimes with bronze tints.

Identifying Dragonflies from photographs

If you can't identify a Dragonfly species in the field try taking photos of the specimen so you can identify it later, either by using this online guide, a guide book or by submitting an ID query. In order to capture all the important features of a species, and to make identification as easy as possible, try to get at least two photos: one taken from directly above and one from the side of your subject. 

Below are examples using a male Southern Hawker. In these photos all the important ID features are in focus.
