White-legged damselfly

A quick trip out to Southwater country park this afternoon and I found this beauty + several others flying around the long grasses in Ben's field.
The White -legged damselfly platycnemis pennipes, is so called because the adult males have obvious expanded white legs which they use in a 'fluttering' display in front of the females. 
The males are pale blue when adult and the females pale greeny cream.
It is listed as uncommon, but can be locally abundant in some places, which is the case round here.
