Comma, say (9)
I believe the answer is:
butterfly
'comma say' is the definition.
(I know that Polygonia comma is a type of brush-footed butterfly)
This is all the clue.
(Other definitions for butterfly that I've seen before include "Insect with four coloured wings and feelers" , "Beautiful insect and swimming stroke" , "Idea that a small change can have major consequences elsewhere" , "Swimming stroke - sort of net, kiss or screw" , "Insect; flighty person" .)
