|The Beautiful Demoiselle (Calopteryx virgo) is a European damselfly. It is often found along fast-flowing waters where it is most at home.|
The Beautiful Demoiselle lives mainly near small to medium sized streams and creeks. They prefer a relatively low water temperature and a moderate to fast flow. The water must not be nutrient rich (eutrophic). In the northern part of their range, such as in Norway and Finland, it is also found near medium-sized rivers or even larger streams. The waters are usually in the immediate vicinity of forests.
The distribution of the Beautiful Demoiselle covers all of Europe with the exception of the southwestern Iberian Peninsula, the Balearic Islands and Iceland. In the north it extends to the Arctic polar sea, and thus much further north than that of the banded demoiselle. On the North African Mediterranean coast, its southern populations in Morocco and Algeria can be found. The northern boundary in Asia following the 13-°C July isotherm, it is therefore not in the areas where the average temperature in summer below 13 °C falls, otherwise they are met with in temperate and cool regions in the entire continent with the exception of deserts and the mountains of. The eastern subspecies of C. v. japonica found on the Japanese islands is under debate as to whether it is a separate species. The Beautiful Demoiselle is mostly found in lowland locations. Regular findings come from areas up to a maximum height of 980 m above sea level. Occasionally they may be found up to 1,200 meters in altitude, such as in the Alps.
The male usually has much more extensive pigmentation on the wings than other Calopteryx species in its range: in the south east of its range (the Balkans and Turkey) the wings are entirely metallic blue while in other areas, there are clear areas at the base and tip of the wing. Immature insects often have much paler, browner wings. They have metallic blue-green bodies and blue-green eyes.
The female has dark brown iridescent wings, a white patch near the tip of the wings (called a pseudopterostigma) and a metallic green body with a bronze tip of the abdomen.
Eggs and larvae
Females lay up to 300 eggs at a time on emergent or floating plants, often on water-crowfoot. Like the Banded Demoiselle, they often submerge to do so. The eggs hatch after around 14 days. Again, like the banded demoiselle, the larva is stick-like with long legs and develops over a period of two years in submerged vegetation, plant debris or roots. They usually overwinter in mud or slime.
The larvae of the Beautiful Demoiselle develop over 10 to 12 stages, each of which takes place between a molt. The body length is variable and highly dependent on environmental conditions. The final stage (F-0-stage) larvae are 3.5 to 4.6 millimeters and weigh about 4 milligrams, slightly below the Banded demoiselle. Apart from the larvae of the demoiselles are difficult to distinguish from each other, the apparent differences lie mainly in the bristles and the severity of the tracheal gills on their abdomen. Compared to other damselflies demoiselles larvae fall immediately on the other hand, due to their much shorter mean gill lamella.
The body of the larvae shows only a relatively small adjustment to the fast-flowing waters of their habitat. The body is not flattened but very slim and turning around, the legs are long and have its end with strong claws, with which it can be stated in the vegetation. Because they reside within the water body, but mainly in the quieter areas, the danger of being swept with the flow, is relatively low. If this happens, they clearly its long body and legs stretched as far as possible to get in touch with the vegetation or the substrate to come.

Hi Peter,a very common specie in my country too but always difficult to take in a perfect way because its terrific blue full of reflections,your pic is good but the sharpness seems better on the grass wire and not on the damselfy that looks a bit blurred.Have a nice evening and thanks,Luciano
It's indeed a 'beautiful' creature, neighbour Peter.
The texture, colour and patterns on the blue wings are very well captured.
The diagonal composition with a green blade of grass for perch is aesthetically at its best.
Thanks and regards.

Beautifully made and wonderfully isolated-great!
mooie foto met super mooie kleuren
het is een lastige om hem op de foto te krijgen
tenminste dat heb ik altijd
er waren weer problemen om een foto te plaatsen op TN
Ciao Peter, lovely diagonal composition with elegant damselfly, fantastic metňllic colors, superb sharpness, splendid light and fine details, very well done, my friend, ciao Silvio

Nice composition and details.
Excellent macro of this insect, with fine POV, the diagonally framing
bringing dynamism to the photo, great focus, sharpness, details, TFS
Beautiful colored Damselfly. Well captured keeping BG dark. Good sharpness and well composition too.
Thanks for sharing with informative NOTE,
fine capture of damselfly, great diagonal composition,
very beautiful light effect of wings and abdomen
superb sharpness and colors
have a good night
you captured the blue Demoiselle male very well.
The compostion are great, a classic with the diagonal.
The sharpness of the insect could be better if you used a macro-lens, not easy with a long zoom.
But the DOF is very good, the subject stand out nicely from BG.
Fine nice colours too.
Well done, my friend.
The composition's great in my opinion, so are colors and background blur. But the focus is rather on the leaf than on the nice metallic wing, which seems soft yet oversharpened at the same time. A pity, because the scene's wonderful.
Best regards, László

A beautiful specimen, reminds me of the Ebony Jewlwings we have here in Ohio. Love the gorgeous iridescent colors and intricate textured markings in it's wings. The diagonal composition is great and exposure is perfect. Maybe a tad soft on detail near it's head, but still a pleasing shot.
