Greenfly (5)

Ross

I think it could be either:

aphid

aphis

'greenfly' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for aphid that I've seen before include "Small plant-sucking insect" , "insect pest" , "Fly" , "Small insect like greenfly" , "Blackfly or greenfly" .)

I've seen this clue in The Times, The Daily Mail, the Evening Standard and The Mirror.
