Sometimes you just have to photograph what’s on or in the flower. The first butterfly is a cropped down image of one of my favorite photos of all time. I think you may recognize it as part of the banner of WoolyandRaeski.com.

Nice Flower
Wonderful macros here. I would have to say the poppy is my favorite. But it was hard to choose.
Thanks Cee. The poppy is my second choice. The grey butterfly is my favorite because of all the elements involved. A flower with water drops, an unusual butterfly, good color, and nice bokeh.
