Cunning insect (3)

I believe the answer is:

fly

I believe this clue is a double definition.

'cunning' is the first definition.
(fly can mean skilful or sharp)

'insect' is the second definition.
(fly is a kind of insect)

(Other definitions for fly that I've seen before include "Knowing, insect" , "Dipterous insect" , "Two-winged insect" , "Soar; hurry" , "Travel through the air" .)

I've seen this clue in The Times.
