El Segundo blue butterfly

A federally endangered species, the El Segundo blue butterfly depends on the coast buckwheat plant at each of its four life stages (egg, larva, pupa, and adult). Air Force biologists implemented surveys to document El Segundo blue butterflies across more than 1,200 acres on-base and extended their monitoring efforts to include 198 acres of adjacent state-managed lands. These monitoring activities provide instrumental data needed to improve overall recovery efforts for this federally endangered species.
