playing with the iso (42)
|Sympetrum sanguineum / Ruddy Darter female /.|
Common name: Ruddy Darter
Preferred environment: shallow well-vegetated lakes and ponds often in woodland. In Ireland associated with pools in fens and cutover bogs, small base-rich mesotrophic lakes and turlough-like lakes.
Flight period: mid June to mid October. In Ireland early June to mid September.
Adult habitat and habits: adults perch on edge of open spaces when feeding. Mature males occupy perches near breeding sites and defend small area around them. Perches often changed if no females encountered. Females are intercepted as they approach breeding sites and taken in tandem by males to bushes for copulation.
Oviposition site and behaviour: females oviposit usually when in tandem with male, over open water, clumps of plants or exposed muddy margins by dipping abdomen on water surface to wash off batches of eggs.
Larval habitat and habits: eggs either hatch within a few days of laying, or if laid late in season eggs will diapause until spring. Larval development takes one year. Larvae live amongst roots of aquatic plants including Typha and Equisetum.
Emergence behaviour: on vertical plant stems in early morning.
Range: southern and central Europe to southern most Fennoscandia, and to western Siberia. Absent from most of Mediterranean islands, southernmost Iberia and Italy. Very local in north Africa. In Ireland found as far north as Lough Neagh but principally in Midlands and Burren.
Determination of adults: species is keyed and diagnostic characters are figured in Askew (1988); mature adults are illustrated in colour in Askew (1988) and Brooks (1997).
Determination of larvae: keys to mature larvae in Askew (1988) and Brooks (1997).

Widespread and locally common in suitable sites. Adults can be seen between mid June and September. The Ruddy Darter is found in fens, cutover bogs and small lakes including turloughs. There is some evidence for immigration.
This species is most likely to be confused with the Red-veined Darter Sympetrum fonscolombei and the Common Darter Sympetrum striolatum however the latter is more orange-red and has a straight sided abdomen and yellow stripes on the legs. Female Ruddy Darters are similar to female Black Darters Sympetrum danae however in the former there is no black triangular marking on the thorax.
KEY IDENTIFICATION FEATURES:
-mature males have noticeably waisted blood-red abdomen
-females dull yellow brown
-legs all black in both sexes
I said it by the title. I have played with the iso here. I had it here on 800 iso. and I must say what a quality for this high. I hope you like the pov and the quality. Have a nice day.
