Damselflies

 

 

 

Small Spreadwing

Lestes virens virens

Lestes menor
 

Mating pair of Small Spreadwings. Male at top of picture. Note that this sub-species has bicoloured pterostigmae. A pterostigma is a cell in the outer wing of an insect that is thickened or coloured and so stands out from other cells - particularly notable in many dragonfly species. They assist in gliding flight by controlling wing vibrations that would slow the speed of the insect.

 

Common Winter Damsel

Sympecma fusca

Libelinha hirbernante
 

Hibernating adults of this species characteristically have blue eyes, as here.

Common Blue Damselfly
