BEST COMEBACK (ANIMAL KINGDOM) Miami Blue Butterfly Once more prevalent than cars on 836, the Miami Blue (Hemiargus thomasi bethunebakeri) wasn't doing so well thanks to humans and, mostly, their always encroaching development. (Habitat loss, natural disasters, and mosquito-reduction spraying are the three biggest destroyers of little flying things in South Florida.) It was even thought to be extinct after Hurricane Andrew charged through in 1992, but the bug was still hanging on -- roughly 50 of them hiding out at Bahia Honda State Park. The tiny blue-winged insect was destined to be wiped out during the next big blow, but thanks to a University of Florida breeding program, the Miami Blue is on the rebound instead. Several generations have been bred in captivity and hundreds were recently released into the wild.
