The Florida Museum of Natural History is hosting the seventh-annual ButterflyFest Facebook Photo Challenge! Submit your best picture incorporating metamorphosis by Sept. 23 for your chance to win prizes. This free challenge is open to all ages. The museum will post the top 10 images from entries received on its Facebook page on Sept. 30, and the public will select the overall winner online via the most “likes.” The museum will recognize the winning photograph during ButterflyFest on Oct. 12.
