An explanation is necessary for this list. The BDS list of UK species seems ambiguous in that it includes pure migrants whilst I want a list of UK resident species.
I began with the 44 species of Odonata taken from Britain’s Dragonflies (Smallshire and Swash). These were the so-called “breeding species”. However, that included Sympetrum flaveolum (Yellow-winged Darter), with which I disagree; S. flaveolum has, in the past, invaded our shores on a few occasions and apparently has bred but at the time of editing [2018] it hasn’t been seen for more than 20 years – it certainly ain’t resident IMHO.
Conversely, over recent years we have consistently seen a few newcomers in the UK. Both Lestes barbarus (Migrant Spreadwing/Southern Emerald Damselfly) and Aeshna affinis (Blue-eyed Hawker/Southern Migrant Hawker) are now established in Kent and/or southern Essex. Originally regarded as migrants, they certainly now appear to be breeding residents. Coenagrion scitulum (Dainty Damselfly), having once been a resident species that was thought to have been wiped out, was rediscovered in 2010 and is now apparently surviving on the Isle of Sheppey but is on a private site with only the county recorders apparently having access. So, these I have included in my resident list. The list also includes Anax parthenope (Lesser Emperor) as a yearly visitor rather than as a breeding resident. Thus I have ended up with my UK list of 45 species.
Species which are linked to a species page, I have seen (though not necessarily in the UK). Unlinked entries, I am yet to see. As a result of a successful though weather-plagued trip to Scotland in 2017, I am now down to one species remaining to be seen.
