First two shots are a good start. Pity the specimens have torn and tattered wings.
Just remember, as much as possible, try to shoot as parallel to the plane of the wings/body of the butterfly, to get as much in focus as possible. Best are to aim for the eyes as the focal point, because even if the rest of the image is not so much in focus, the shot is always saved a bit if the eyes are in focus. And also try to look for uncluttered bright background, to get nice bokeh. But all these are in theory, in the field its quite hard to achieve such ideal situations. So we all just try our best.
