[Note Guidelines] Photographer's Note
The red-veined darter (Sympetrum fonscolombii) is a dragonfly of the genus Sympetrum. It is a common species in southern Europe and from the 1990s onwards has increasingly been found in northwest Europe, including Britain and Ireland. Its name is sometimes spelt fonscolombei instead of fonscolombii but Askew (2004) gives the latter as the correct spelling. There is genetic and behavioural evidence that S. fonscolombii is not closely relate to the other members of the Sympetrum genus and will at some time in the future be removed from this genus.

S. fonscolombii is similar to other Sympetrum species but a good view with binoculars should give a positive identification, especially with a male. Males have a red abdomen, redder than many other Sympetrum species. The wings have red veins and the wing bases of the hind-wings are yellow. The pterostigma are pale with a border of black veins and the underside of the eye is blue/grey. The female is similar but the abdomen is yellow, not red, and the wings have yellow veins, not red veins as found in the males. The legs of both sexes are mostly black with some yellow. Teneral males are like females but often with more red.

Male S. fonscolombii can be mistaken for Crocothemis erythraea as both are very red dragonflies with yellow bases to the wings, red veins and pale pterostigma. However C. erythraea has no black on the legs, a broader body and no black on the head. Also C. erythraea females do not oviposit in tandem.

S. fonscolombii can be seen on the wing throughout the year around the Mediterranean and in the south of its range, however, its main flight period is May to October and it is scarce during the winter months. It is a territorial species with the males often sitting on an exposed perch. After copulation the pair stay in tandem for egg laying and pairs can be seen over open water with the female dipping her abdomen into the water depositing eggs. Pairs are known to fly over the sea in tandem dipping into the salt water where the eggs soon perish. The eggs and larvae develop rapidly and S. fonscolombii unlike most other european dragonflies has more than one generation a year.

Hallo buurman,
Erg mooie foto in heldere kleuren. De foto is enorm scherp met prachtige details. Jammer dat er ietsje ruis in de achtergrond zit. Goede vage achtergrond en compositie.
Geniet van de zondag,
Peter

bonjour hans
bonne netteté et bonne gestion de l'exposition toutefois je pense qu'un cadrage plus panoramique lui aurait preferable car le haut de l'image n'apporte rien a mon sens.
