Mandibles are the jaws of the caterpillar. The mandibles bite off plant material and tear it into small, easily digestible pieces. Adult butterflies do not have mandibles.
Johnston's organ is an organ at the base of a butterfly's antennae. This organ are responsible for maintaining the butterfly's sense of balance and orientation, especially during flight.
The jugum is a descending lobe of the forewing of some moths that overlaps the hindwing, holding the two wings together when in flight.
The Julia is a yellow-orange tropical butterfly with long forewings. It is about 3-4 inches wide. The female Julia is a duller shade of orange and has more dark markings. The small, yellow-to-gold eggs are oval. The pupa is angular. The Julia caterpillar feeds on passion flower vine (Passiflora); the adult sips nectar from the flowers of the lantana and shepherd's needle. Julias are found from South and Central America to the southern USA. The Julia belong to the Heliconians, tropical butterflies that have a bad taste and smell, and a large head. It is a brush-footed butterfly (Family Nymphalidae).
A jumping bean is a seeds pod in which a caterpillar lives. When the caterpillar moves, the seed pod moves. The caterpillar will turn into a moth (Cydia saltitans) eventually. The Jumping Bean Moth is native to deserts and other areas of Mexico.
