Identification:
Similar species:
Life stages:
After an initial mating ritual the mating act takes place near the water and lasts a few minutes. The solo female then inserts the eggs into submerged plant material. The eggs hatch after few weeks. The larvae live in-between water plants and develop over 2-3 years. The imago transformation takes place near the water on plants, up to a meter above the ground.
Distribution: (?):Altitude is often taken from a specific localized resource, why the true entire range very likely is wider.
Most of Europe eastward through Russia to the Ural Mountains. Also patchily Turkey and Iran. Very local NW Africa. In Denmark mostly present in S Jylland and on Bornholm.
Habitat:
Behavior:
Male guards over female while egg-laying.
Host plants:
Vandpest (Elodea)
Vandranunkel (Batrachium)
Pindsvineknop (Sparganium)
Endemic:
Status:
Main distribution range in Denmark is the southern part of Jylland north to Limfjorden. Also relatively common in Nordjylland and on Bornholm. Rare elsewhere. Many observations in the citizen portals away from Jylland and Bornholm are, or very likely are, erroneous. Municipalities not housing any confirmed observations are excluded from the dk-map. These are mainly from Sjælland. Rather common and widespread in Sweden and Finland, less so in Norway.
Comment:
Measurements (taken from Dijkstra and Schröter 2 edition) seem to be off!

Splendid creature! Here seen perched on firs several hundred meters from the nearest water source - something both species do occasionally.

This new Danish species probably didn't receive the attention it deserved, being such so beautiful as it is . But I was more focused on the other two new Danish species present at this spot...

Notice the slight paleness, transparency, near the wingtip. Not sure if it is related to population or individual variation.

2 different males.
I had three males in all on a day with very little activity.

Imago Female
Both Beautiful and Banded can be seen here. And both species can be seen away from water roosting in forest trees like here.

We only had few of the species, and again along forest roads and clearings.
