The White-faced Darter (Leucorrhinia dubia) is a small dragonfly belonging to the genus Leucorrhinia in the family Libellulidae. Its flight period lasts from May to August. It is found in peat bogs from northern Europe eastwards to Siberia. In southern Europe there are populations in some mountainous areas such as the Alps and Pyrenees. In Great Britain it is rare and local with the largest population in the Scottish Highlands.

The abdomen is 21-27 mm long and the hindwing is 23-28 mm long. Mature males have a black body with red and orange markings on the abdomen and thorax which become darker with age. Young males and females have pale yellow markings. All have a conspicuous white frons at the front of the head. The wings have a brown patch at the base.

It breeds in acidic pools with extensive growth of Sphagnum moss. The male holds a small territory near water. Copulation with the female often begins over water before they settle on the ground or in low vegetation for about 30 minutes. The female drops the eggs amongst submerged moss or the stems of cottongrass. The larvae live amongst the Sphagnum; they feed mostly at night but are also active during the day. They take one to three years to reach adulthood with two being most common. They emerge between May and early July, climbing out of the water up a plant stem before flying away from the pool. Males become mature 4-12 days after emergence and females a few days later.

Hi and Good Morning Hans,

Excellent job with the focus, it looks nice and precise.
Such a well suited flat background for the dragonfly to stand out against, it all looks well composed too.
This pretty d-fly also a novelty for me too.
TFS and have a nice day MF!
Cheers,

Bayram

Hola Hans,
primero gracias por tu ayuda en la corrección de la ID de mi libélula; veo que hay varias e interesantes además en tu corta pero buena galería.
Esta que nos presentas interesante, además bien centrado el foco en la zona de las alas, lo que da fuerza al conjunto.
Buena luz.

Saludos: Josep Ignasi.
