Butterflies are the essence of cool in the insect world, a favorite muse for poets and songwriters who hold them up as symbols of love, beauty, transformation and good fortune.
But providing good fortune apparently goes only one way. As humans rip apart woods and meadows for housing developments and insecticide-soaked lawns, butterflies across the US are disappearing.
The US Fish and Wildlife Service recently announced that two brown, moth-like butterfly subspecies are likely extinct in south Florida, which some entomologists say is ground zero for the number of butterfly species on the verge of annihilation.
The rockland grass skipper went missing in 1999, and the Zestos skipper hasn't been seen since 2004. Several other species, such as the ebony-and-ivory-colored Schaus swallowtail, are listed as endangered, and many others are threatened, including the silvery Bartram's hairstreak.
"We look at it as a signal that we've got a serious problem with butterflies and other insects and pollinators here in Florida," said Larry Williams, a supervisor for the ecological services program at Fish and Wildlife. "We're looking at this as sort of a wake-up call that we need to be watching butterflies more closely."
At least one species of butterfly has vanished from the United States, along with the two subspecies in Florida. Seventeen species and subspecies are listed as endangered nationwide, and two are listed as threatened.
