I know this has been criticised as oof, but I wonder if that is totally true. The body of the butterfly looks to be in focus and was probably the focus point, the wings suffer because

1) The fringe effect that is present on the trailing edges of butterfly wings

2) Because dof is greater behind the focal point, than in front of it the very tips of the wings (particularly on the rhs) are just leaving the area of focus.

I often underestimate how shallow the DOF is in front of the focal point when taking insects, I think that is what has happened here. So right focal point, to low an f-number.

My suspicion is that this image has not been sharpened at all, a touch of sharpening shows just how clear the detail on the body is.
