Damselflies (2): Emerald Green Mystery

Green seemed to be the colour for Damselflies at WWT Llanelli the weekend. A kind photographer pointed out the one below [1], and we soon spotted the rather pale and muted green form of specimen [2].

1] Emerald Damselfly


Can you spot the camouflaged creature
in David's photograph above?
I think it may be the Emerald Damselfly, Lestes sponsa.

I am wondering if [1] is a female, since male Emeralds have blue eyes.

I note that Welsh.lensman had spotted this species in the same location:
his link will take you to the Wild about Britain forum.

Above: details of head and thorax ...
and 'hairy legs'!

2] Green Damselfly


Above: it was almost like a Lacewing in that the wings
were pale and delicate.


I have not been able to identify this Damselfly to date.
Any clues would be appreciated!

Perhaps this could be the female of the Emerald species above?
It seems that Emerald Damselflies usually perch
with their clear unpigmented wings half-open,
so I have my doubts.

Having said that, this link leads to an image
of an example with closed wings.

It is possible that [2] is a female White-Legged Damselfly:
what do you think?
There is an enlarged view here.

Unfortunately my photograph does not show
the Pterostigmata on the wings,
which should be light brown.

It does not seem a very likely identification
if you look at the distribution map.

Who can solve the mystery?
