Here are some skimmers and sympetrums. Thanks for looking, I hope you can identify these. Sardinia June 2018

Red-veined should have an obvious blue, lower half to the eyes.

It also has yellow tibia so Common Darter IMO?

Your right of course.

Interesting update

I was never happy with picture 1 being O. coerulescens and went through the pictures again. I found this one which shows the side of the thorax. This for me was quite a puzzle as it looks nothing like any other Orthetrum illustrated in Dijkstra. A continental friend pointed me in the right direction; it is O. brunneum! The site actually held O coerulescens, cancellatum and brunneum. Sorry for not providing this picture before, but perhaps I am not the only one to learn from this.

I somehow missed this thread

If Lewington illustrated Dijkstra with individuals of all ages then the book would be too big for us to carry in the field!

Attached an immature female Southern Skimmer (O.brunneum) from Spain in September 2015. As they get older they lose the shoulder stripes and so become less 'Keeled'-like.

Thanks again Paul. My example is a male. Interesting stuff!

We are having to wait a long time for the 2nd edition of Dijkstra, do you know if its coming soon? Two books, a paperback for the field and a heavy augmented edition for the desk would be ideal!

The book isn't that old, are they doing a 2nd Ed already?

So it is! I'm not being very observant lately - I looked at the small pterostigmas and the patterns and ignored the appendages. Two young males attached - one getting some pruinosity, the other not, and neither as dark as the one in your photo!

14 May 2020 according to a google search."The second edition includes fully revised regional guides and identification texts, updated distribution maps and conservation statuses, illustrated accounts for five species that have been discovered in the region since the first edition, updated checklists and taxonomy, new photographs throughout, as well as an introduction to larvae identification. Each species is lavishly illustrated with artworks of males, females and variations, as well as close-ups of important characters."

I know Dave Smallshire is working on a European guide although I'm not sure when that is due for publication - it will be good to have a guide with photos as well as drawings.

New editions of both Britain's Dragonflies and Dragonflies & Damselflies of Great Britain and Ireland are due out over the next two months. Always good to spend the pension rather than save it!
