Butterfly caught with slugs around (5)
I believe the answer is:
comma
'butterfly' is the definition.
(I know that comma is a type of brush-footed butterfly)
'caught with slugs around' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'with' is a charade indicator (letters next to each other).
'slugs' becomes 'ammo' (slug can informally mean bullet).
'around' shows that the letters should be reversed in order.
'ammo' backwards is 'omma'.
'c'+'omma'='COMMA'
(Other definitions for comma that I've seen before include "breathtaking marking?" , "repeatedly found in lists" , "identifying place to breathe" , "Clause-separating punctuation" , ", (stet)" .)
