Dragonflies (order Odonata) are divided into two distinct sub-orders, the Zygoptera or Damselflies and the Anisoptera or Dragonflies. In Wales there have been 37 species of Odonata recorded, 15 of these are damselflies and 22 dragonflies. This includes 6 migrant species which are only seen rarely, these species have a turquoise background.
For each of these species, a small photo and the scientific, English and Welsh names are given. The Welsh names were taken from the book 'Cyfres Enwau Creaduriaid a Phlanhigion: 3 - Gwyfynod, Glöynnod Byw A Gweision Neidr' edited by Duncan Brown, Twm Elias, Bruce Griffiths, Huw John Huws and Dafydd Lewis ISBN number 978-1-84527-259-3.

The species information page has photographs, a written description of the species, details of habitat, distribution and status information and notes about similar species. The Vagrant Darter is rarely seen so does not yet have a species information page.
