The algae is followed by weeds and ultimately a silting of water bodies.

In intensively used agricultural areas with a regular input of manure as fertilizer is a few meters wide can prevent extensive or unmanaged riparian strips one Einschwemmung and thus act against eutrophication. They also live in small natural lakes or ponds characteristic for limestones bedrock. The Banded Demoiselle C. The larvae of the beautiful demoiselle develop over 10 to 12 stageseach of which takes place between a molt.

Regular findings come from areas up to a maximum height of m above sea level. In addition, the larvae no holding facilities are against the current, and the algae and dirt particles settle to the gill lamellae are important for respiration. Males who do not occupy spots can keep themselves in the vegetation on the shore and try to mate virgp fly to females or to fill vacant spots.

In addition, the egg of the banded demoiselle at the front cirgo a funnel-like appendix unknown object, which projects at the inserted egg outwardly from the plant stem. Compared to other damselflies demoiselles larvae fall immediately on the other hand, due to their much shorter mean gill lamella.

At the end of larval development, it comes to winter and the development until the following year with the metamorphosis to the imago completed univoltine development.

The habitat that the adults occupy, corresponds to the nearby larval habitat. This species is rather similar to The Banded Demoiselle Calopteryx splendensother British damselfly with coloured wings. Views Read Edit View history.

The males rest on bankside vegetation waiting for females. This species presents an evident sexual dimorphism in colour pattern.

The inefficiency of oxygen uptake is balanced by the choice of habitat, since both increased flow and cooler water absorption capacity. Even a partial thinning of trees and shrubs should be performed. They can be found on submerged plants such as waterweed Elodea sp.

If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The following other wikis use this file: Similar species The Banded Demoiselle C. They usually overwinter in mud or slime.

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. This is mostly meadow and pasture streams in the area, they rarely pass through the forest.

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. The size of the spots and their distance apart is the density of the population dependent as well as the occurrences of the water and may be between several meters and a few decimetres. Among the factors that make a settlement of the water for the larvae of the blue-wing demoiselle impossible to include on the one hand, the channeling and obstruction of the same, go where the lost for the settlement of important aquatic plants.

On the North African Mediterranean coast, its southern populations in Morocco and Algeria can be found. Skip to main content. This aging period usually lasts about 10 days, after which they return to the waters. You are here Beautiful Demoiselle. The body length is variable and highly dependent on environmental conditions. Isarkanal, Munich, Germany Deutsch: A distinct riparian vegetation also plays vidgo role as a windbreak. The tree growth on the waters edge should not report closed canopy, otherwise lack the necessary sunlight.

The larvae live in the streams mentioned before and are mainly cxlopteryx on the water plants. The eggs are laid in the stems of aquatic plants in the water level virog below, where the female can submerge up to 90 minutes.

View all coordinates using: Females fly over during the day, the waters in search of suitable nesting sites, the main activity of both sexes such as hunting, advertising, mating and egg laying occurs in the warm midday hours. The substrate of the river has only a very minor importance, because the larvae reside mainly in the vegetation. This is mainly because they absorb the oxygen from the water inefficient.

The thin-skinned, tracheogenic body attachments for oxygen uptaking from the water, under normal circumstances are still less sensitive to fluctuations in the oxygen supply. The flight is fluttering, butterfly-like. As resting places, the animals need trees and shrubs, often resting on high herbaceous plants such as the large nettle Urtica dioica.

Calopteryx virgo can reach a body length of 49—54 millimetres 1. The blue-winged demoiselle lives mainly near small to medium-sized streams and creeks. The veralgten plants are not accepted by the females as oviposition sites.

The radius calopteyx action and thus the distance between breeding, hunting and rest area is in the males of 20— meters and is therefore very small, the females were observed, however walking distances of up to four miles per day.
