Go on about a bee (5)

I believe the answer is:
drone
This clue might be a double definition.
'go on' is the first definition.
'drone' can be an answer for 'go' (droning is a kind of going). I'm not certain of the 'on' bit.
'a bee' is the second definition.
(drone is a kind of bee)
'about' is the link.
Can you help me to learn more?
(Other definitions for drone that I've seen before include "mollusc" , "Bee, speak tediously" , "Queen bee1s mate" , "Queen's mate" , "Continuous humming sound" .)
