Very nice depth of field. I would run a Sharpen filter over them in PS, though.
Sharpening in PS may look to fake, the images are quite good how they are. My suggestion for future shots would be to stop down the aperture a bit (say f5.6 or f8 light allowing). This would allow you to get more of the butterfly in focus while still maintaining a blurred background, which would fall off due to distance. You may not get quite the degree of blur back there with a smaller aperture (higher #) but it would help get more of the subject in focus.
The first picture, the butterflies' head is quite sharp, but the tip of its wings are a bit soft....again solved by aperture if applicable. The second image is a bit soft everywhere, but not bad. It looks a bit like camera shake as there is not really a single point that stands out as "sharp". Overall though, I really like the pictures, amazing detail on both the flower and the butterfly, nice work.
