My thought is that there is too much background, not enough butterfly. So either crop these or get closer next time you shoot butterflies so that your compositions are stronger and emphasize the insect.
Butterflies are notoriously skittish creatures and sometimes we are stuck with a less than ideal background. So don't be afraid to stage manage your backgrounds in the editor by patching up distracting areas.
On the wings, open up the dark areas just every so slightly so that the wing & scale details are not lost. Then enhance such details with some kind of local-contrast sharpening using a detail slider or a hi-pass overlay or some similar technique. Brush the detail enhancements on the wings where needed so that the background stays soft.
Here is a cropped version of one of your beautiful butterflies with some detail enhancement and a bit of background trickery. I'm *not* saying this is "right", OK??
I'm just putting one possibility out there. You as the artist/photographer are the who should decide where to go with your work.
[These are a bit the worse for the wear because it is not easy to edit a resized jpeg without introducing artifacts, so I hope that Peter only looks at the compositional suggestion. Thx.]
