From ANIMAL PEOPLE, May 1994:
Fourteen years after being
declared an endangered species and 11
years after being pronounced extinct, the
Palos Verdes blue butterfly has been resdi-
covered. University of California geography
professor Rudi Mattoni, believed to be the
last person to see the butterfly before it pur-
portedly vanished, recognized it again on a
mid-March insect collecting visit to the U.S.
Navy’s Defense Fuel Supply Point in San
Pedro. The site is protected as critical habi-
tat for the also endangered California gnat-
catcher, a small songbird.
