The caterpillar in the photo is the larva of the Pacific fruit-piercing moth. You may see them eating the leaves of Erythrina trees (coral trees). They are usually seen beneath the leaves or on the edges. The population is normally kept in check by tiny parasitic wasps called Trichogramma egg parasitoids. The moth stage does the real damage. The adult moth flies at night and sucks out the juices of ripe mango, banana, tomato, melon, citrus, guava, papaya and other fruit with its proboscis (tongue). (Source)
