Move like a butterfly (4)
I believe the answer is:
flit
'move like a butterfly' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for flit that I've seen before include "Moonlight escape?" , "Move house" , "Fly rapidly and lightly" , "it may be done by moonlight" , "Move swiftly and lightly" .)
