Stripped hammock back, revealing insect (5)
I believe the answer is:
comma
'insect' is the definition.
(comma is a kind of insect)
'stripped hammock back revealing' is the wordplay.
'revealing' says the answer is hidden in the clue.
'back' says the letters should be written backwards.
'ammoc' is hidden in the letters of 'stripped hammock'.
'ammoc' back-to-front is 'COMMA'.
(Other definitions for comma that I've seen before include "Butterfly with orange and brown wings" , "List-item separator" , "part of list, invariably" , "Kind of butterfly" , "Brief stop" .)
