STRANGE HABITS OF FAMILIAR MOTHS AND BUTTERFLIES Photograph by David Fairchild HOW A CATERPILLAR STRIKES TERROR TO A FOE The fearsome mien of this larva of a common Swallow-tail Butterfly (greatly magnified) is only camouflage. The real head of the insect is the small semicircular segment at the bottom of the picture. The huge "eyes" are only make-believe (see text, page 91). Photograph by Graham Fairchild A JAVA COUSIN OF "SAMIA CECROPIA" The antennae of moths and butterflies are believed to be the aerials through which they receive the calls of their distant mates. The photograph is greatly magnified.
