The Eudocima fullonia is a type of butterfly found in Australia. The caterpillar can be orange, brown, or black with white spots and orange markings. It will show two eye spots when it feels threatened by curling its head and lifting its tail. This can make it look like a face with a wry mouth.

Adult moths have light brown front wings. Male moths have a weak pattern of light and dark spots. The fruit-piercing moth has lived in Hawaii for almost 20 years and even longer in the Pacific Basin area. It is not considered a big problem in Hawaii, but it is in the Pacific Basin, so using Tropic Coral as a windbreak is not recommended. If you need to stop the caterpillars from damaging the Erythrina trees, the natural pesticide called Bacillus thuringiensis (BT, Dipel) should help. However, you usually don't need to spray to control the caterpillars because the parasite population will grow and fix the problem. It is best to talk to an Extension Agent for advice on preventing them.

Females have a complicated design on their forewings that includes a small white triangle close to the center and a pale line across the wing. Both males and females have bright yellow hindwings with a wide edge and a big dark comma in the center.

Both males and females have a yellow band on the bottom of their front wings. The base and top of their back wings look the same.

The picture shows a Pacific fruit-piercing moth larva. They eat leaves from Erythrina trees (coral trees) and are often found on the leaves or their edges. Usually, tiny wasps called Trichogramma egg parasitoids keep their numbers under control. But, strong winds and heavy rain, like what happened in Hawaii in 2004, can make the wasps ineffective. It may take a month for them to start working again. This kind of outbreak doesn't happen in the same place every year.

The moth stage is responsible for the real damage. At night, the adult moth flies and uses its proboscis (tongue) to suck the juice out of ripe or almost ripe fruits such as mango, banana, tomato, melon, citrus, guava, papaya, and others. The fruit doesn't have to be fully grown, just soft enough for the moth to pierce through. This results in a brown, circular, and rotten spot forming around the tiny hole and the fruit becoming useless for commercial purposes.
The female moth lays yellowish-green eggs on the underside of the leaves of trees in the genus Erythrina, such as the "Tropic Coral" tall erythrina, Hawaiian wiliwili, tiger's claw, gaogao (Guam), gatae (Samoa), and parepein (Pohnpei). The caterpillars, or larvae, hatch and feed on the leaves. They are 2-3 inches long, green to rich brown-black, and have two eye spots on each side. The pupae form among the leaves, shining brown-black with a purplish tint. The moths come out of the pupae. The whole cycle, from the hatching of eggs to adult moths, takes about 30-60 days, depending on the weather.
