Butterfly operating strangely (6-3)
I believe the answer is:
orange-tip
'butterfly' is the definition.
(I've seen this before)
'operating strangely' is the wordplay.
'strangely' indicates anagramming the letters.
'operating' is an anagram of 'ORANGE-TIP'.
(Other definitions for orange-tip that I've seen before include "Butterfly variety" , "British butterfly" , "Common butterfly" .)
