These are very spectacular and colorful shots which demonstrate how useful P&S cameras are for macro photography.
Yet, there is a flat, 2-dimensional effect to the butterflies which I assume is due to the camera being used (in macro mode) with telephoto lens fully extended.
Is this the case? I don't have much experience using P&S cameras, which is why I ask. However, I can see that it might not be possible to get closer using a shorter focal length because the butterfly would take off.
It would be interesting to compare two macro shots of something that is stationary or unable to fly away, using both the short end and the long end of the lens.
