I like the mimics, the bee mimics and the hoverfly mimics, I think they are so interesting. Here you did a great job on the exposure and the detail and sharpness are good too. I like the angled comp also. I would have liked to see the whole wing tip and maybe a better looking perch. A good quality perch can really make the shot. The midnight background is not for me but thats a personal preference.
Nice capture and good detail on the bee - if I may add to the BG discussion - I tend to ride the fence, but to me the background works and helps puts more emphasis on the insect and flower.
