Check marks the spot! A recovery program for one of the rarest butterfly species in Southern California, the Quino checkerspot, has reached an important milestone. A team of biologists from the San Diego Zoo, U.S. Fish and Wildlife Service (USFWS), Conservation Biology Institute and San Diego State University observed multiple adult butterflies, following the first-ever release of larvae into their native range in the San Diego Wildlife Refuge earlier this year. The sightings of adult butterflies in the habitat is an early sign of success for the recovery effort for this precious pollinator.
