Turned into an insect, getting caught in the morning (6)
I believe the answer is:
became
'turned into' is the definition.
('become' can be a synonym of 'turn into')
'an insect getting caught in the morning' is the wordplay.
'an insect' becomes 'bee' (bee is a type of insect).
'getting' is an insertion indicator.
'caught' becomes 'c' (cricket abbreviation).
'in the morning' becomes 'am' (AM on a clock).
'c'+'am'='cam'
'bee' placed around 'cam' is 'BECAME'.
(Other definitions for became that I've seen before include "Turned into" , "Developed into something" , "Looked good" , "Suited" , "Underwent a change" .)
