ID

On my part I am afraid it was ignorance. I used M Chinery's book for ID. Since your question I have checked online and by population abundance and coverage it seems most likely to G. jaculator or G. assectator, but I don't know what the distinction is between these two. Do you? Anyhow, sorry...... please feel free to reduce ID to genus if you can't tell from the photo.

G. jaculator

on balance of probability likely to be this species, since it is by far the commonest species where the female has a long ovipositor (assectator has a short one).
