Odonata is the scientific term for the order of insects comprising dragonflies (Anisoptera) and damselflies (Zygoptera). See Dragonfly or Damselfly for an explanation of the difference between a dragonfly and a damselfly.
Odonata is sometimes Anglicized into “odonates” but it seems to be becoming more fashionable to use “dragonflies” as the collective English/common term forcing the rather ugly [my opinion] term “true dragonflies” to be used for, well, dragonflies. I stick to Odonata or Odos for short. Besides, the word lends itself to irresistible puns like “Odo-nutters” (us) and “Odo-natter” (the blog). 😯
In my view there are 45 species of breeding Odonata in the UK. According to Grand/Boudot, there are 89 in mainland France, i.e. within relatively easy and fun (for us) reach; we travel there often. Carol having caught the dragonfly bug as well – if you can’t beat ’em, join ’em – our catalogue outgrew our usual one page photo album, in addition to which I wanted to record other details, such as what species we’d seen where and flight periods. Hence this site dedicated purely to the delightful dragons and damsels.
Our Galleries section present a 1-page of all our damselflies and another 1-page summary for our dragonflies, mainly based on our better photographic efforts. It is English/common name based and enables paging through the various collections easily.
Our Species section dedicates a page to each species keyed by scientific/binomial names rather than English/common names. This decision was based on my hoping to see species further afield for which there may be no English name. [Fingers firmly crossed!]
