The White-legged Damselfly (Platycnemis pennipes) is a damselfly of slow-flowing, muddy waters. It is much more restricted in range than the Banded Demoiselle which it invariably accompanies.


Morphology

Mature adults differ from most other blue damselflies in having expanded white edges to the tibiae, paired black markings down most of the abdomen, broad pale brown antehumeral stripes and a pale brown pterostigmata.

The male has a blue abdomen that is often pale and usually has a greenish thorax.

The female is a very pale yellow-green colour with black markings.


Breeding

This species favours unshaded slow-flowing sections of muddy rivers with abundant floating vegetation. it has been recorded in tidal rivers and the larvae seem well able to tolerate brackish water. It also occurs in muddy streams but is rare in lakes or ponds of any sort.

Mating is preceded by the male displaying his white legs. Elongated eggs are laid whilst in tandem, into emergent stems and especially the underside of floating leaves. The larvae live amongst bottom debris and emerge after two years.


Behaviour

After emerging, adults tend to congregate in the shelter of tall vegetation, although some immatures wander away from water and have been found five kilometres away from the nearest breeding site.

Impresionante acercamiento Nikos, y más teniendo en cuenta el pequeño tamaño en anchura de este insecto. Original y efectiva pose y encuadre con unos colores muy fieles.
