Bee or butterfly (6)
I believe the answer is:
insect
I believe this clue is a double definition.
'bee' is the first definition.
(thesaurus)
'butterfly' is the second definition.

(Other definitions for insect that I've seen before include "Cricket perhaps" , "Member of the largest class of creatures" , "Bug" , "The entomologist studies this" , "Perhaps nit" .)
