Aeshna cyanea

Referred to in Dijkstra/Lewington as Blue Hawker with Southern Hawker as an alternative.

What is the officially accepted source for nomenclature?

ICZN

There is only an officially accepted source for nomenclature for scientific names.

Call them whatever you want when using the vernacular (but always give the scientific name at least once to avoid ambiguity).

Names

What David said! ;0)

Scientific names are the officially accepted standard, and the rules applying to scientific nomenclature try to ensure that each scientific name only applies to a single species (although this falls down slightly when species are 'split').

Most species have a wide variety of English language names that can be applied to them, especially if they are widespread species, although one or two names do generally end up being used most frequently.
Of course, you then also need to consider all the different names used in other languages!

For dragonflies, the names used by the British Dragonfly Society are now well established for use in the UK, but many of these names do not transfer well for use in Europe - which is why Dijkstra/Lewington coined 'new' names, and/or used English names already in use in other parts of the world in their book (the first to give English language names to all of Europes' dragonfly species).

What's in a Name...

Thanks Roy for casting some light on this confusing subject. I guess the best thing is to use BDS names for UK odos and Dijkstra for European ones.

And I thought that species identification was the hard part!
