Insect's male, it's chewed up (6)
I believe the answer is:
mantis
'insect's' is the definition.
(mantis is a kind of insect)
'male it's chewed up' is the wordplay.
'male' becomes 'man' (I've seen this before**).
'chewed up' is an anagram indicator.
'its' anagrammed gives 'tis'.
'man'+'tis'='MANTIS'
(Other definitions for mantis that I've seen before include "A praying . . . . . . is a kind of grasshopper" , "may be praying" , "Predatory insect" , "Praying ..., long-bodied, large-eyed insect" , "Carnivorous insect, which rests as if in prayer" .)
