Insects surround fellow anyway (7)
I believe the answer is:
besides
'anyway' is the definition.
(synonyms)
'insects surround fellow' is the wordplay.
'insects' becomes 'bees' (bee is a kind of insect).
'surround' means one lot of letters goes inside another.
'fellow' becomes 'sid' (Sid is a man's name).
'bees' going around 'sid' is 'BESIDES'.
(Other definitions for besides that I've seen before include "Anyway" , "Apart from" , "Moreover" , "In addition, as well" , "to boot" .)
