Biter destroyed native group (5)
I believe the answer is:
tribe
'native group' is the definition.
(I've seen this before)
'biter destroyed' is the wordplay.
'destroyed' is an anagram indicator.
'biter' is an anagram of 'TRIBE'.
(Other definitions for tribe that I've seen before include "Group of related people" , "Clannish group" , "Group of common descent, culture etc" , "Breed" , "Ethnic grouping" .)
