Bug likes eating fruit (4)
I believe the answer is:
ugli
'fruit' is the definition.
(I know that Ugli is a fruit)
'bug likes eating' is the wordplay.
'eating' indicates the answer is hidden within the clue.
'UGLI' is hidden within 'bug likes'.
(Other definitions for ugli that I've seen before include "Tropical fruit" , "(Repulsive-looking?) fruit" , "Black/violet element" , "so to speak, for > fruit" , "Grapefruit/tangerine hybrid" .)
