I'm not sure why the end of the left wing is out of focus and other areas on the same plane are sharp. Any advice? Thanks.

Very pretty butterflies! Very nice. The sharpness issue is most likely to be the depth of view. Usually, for typical digital cameras, the smaller the iris, the bigger the depth of view...ie more things in focus. Eg, set higher aperture values... like f/8. You'll notice that if you set lower values, like f/2.8 .... the focus can be quite sensitive to subject distance from the camera.

Thanks for the feedback Kenny. You are right, I just over did it because I was trying to obtain a good dof. It just kills me because I like the first one a lot and the out of focus wing drives me nuts! Thanks again!

To be honest, i prefer the second pic.

Bettervariety of colours on the butterfly, and the plantis more interesting. The whole picture just falls into place beautifully. (Only a amateurs opinion though)

DOF is tough on moving targets, if you are using a slr type camera it probably has a dof preview button on it, use it if you can, that is why it is there. You are looking to have the subject sharp and everything else mostly not sharp. If you are using a zoom lens, try different focus points on your shot, like bracketing but with focus. This will place the subject in different places for dof purposes.

The second was very nice, good colors, good lighting.

second shot is very nice, but it looks to me like the image is distorted... like it's compressed horizontally, but not vertically.

the DOF issue could be a result of lens settings (wider aperture to compensate for poor light), or, if you were using a close-up lens, the type of lens could cause that. some inexpensive single-element lenses tend to lose focus at the edges. if you use a single element close-up or macro lens, try to keep the subject in the middle, and leave some room around the edges in case the image isn't as sharp there.

as has been mentioned, aperture is everything in the world of macro. smaller apertures are the only way to ensure reasonable DOF and focus in macro work. if you need to, it's well worthwhile to use a tripod for macro work if at all possible, to let you use those smaller apertures to get clear, sharp photos...

Thank you for the tips squirl. I am only now really trying to understand this wonderful world of photography. I will keep shooting & posting!
