Go on at 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 unsure of the 'on' bit.
'a bee' is the second definition.
(I know that drone is a type of bee)
'at' acts as a link.
Can you help me to learn more?
(Other definitions for drone that I've seen before include "Queen bee1s mate" , "small creature" , "Monotonous low sound" , "Unmanned aircraft" , "Male honey bee, an idler" .)
