Platycnemis pennipes Pallas, 1771 ♂♀
Common names: White-legged Damselfly [En], Agrion à larges pattes [Fr], Blauwe breedscheenjuffer [Nl], Blaue Federlibelle [De]

IUCN Status: LC (Least Concern)

Kerkini, SERRES ● Greece

Description: Length: 36mm. Adult males have obvious expanded, white legs which are used in a fluttering display flight in front of females. The male is pale blue with paired black markings on S2-6. S7-10 are more extensively marked with black. The female is very pale, creamy white when immature becoming pale green with paired black marks on each segment of the abdomen. The ante-humeral stripes are quite broad with narrow, paler stripes below and a medial pale line on the thorax. The pterostigma is pale brown.

Biology: Mating is preceded by the male displaying his white legs in a fluttering display flight in front of females. 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.

Habitat: 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. In north-west Europe, it is mostly confined to flowing waters.

Distribution: Europe except extreme North, Western Asia up to Kyrgyzstan, Syria and Lebanon.
