Female?

Although this is certainly not the easiest angle from which to identify the sex of this species, this one is actually an immature male (not a female).

If you look closely at the appendages at the end of the abdomen you (will hopefully) be able to see that there are two narrow appendages, which are widely separated and angled slightly outwards, these are the 'claspers' which are used to grip the female during mating.
Females also have appendages at the end of the abdomen, but these are slightly wider & closer together, and point backward (see the full sized image here - which you may need to enlarge by zooming in with your browser: http://ispot.org.uk/node/103829 ).

Immature males are green on the thorax.
