With the body covered with bristles, this species has sexual dimorphism in adults, and their larvae may show a yellow, gray or brown color, regardless of gender. It feeds by scraping the surface of the leaves, eventually build a cocoon of silk in the final moment of their development, which becomes pupa.

Host plant: Habitando amendoeira Combretaceae.
● Pic 1, Individual in its penultimate instar, before becoming adult. The lateral expansions are not legs, Phobetron moves as the slug .
● Pic 2, The same individual from the first picture, walking in my hand. Phobetron is not poisonous or stinging.
● Pic 3, The same individual who is in the pictures 1 and 2, now in its last instar before becoming adult, walking on a surface of transparent glass.
● Pic 4, The larvae at different instar on leaf of the host plant.
● Pic 5, Ventral (anus of the caterpillar) I do not know what are the white spots. I believe that the dark spots are food traversing the digestive tract, from mouth to anus.
● Pic 6, Ventral ( head of the caterpillar.) The head is retractable, is hidden beneath a skin or "hood".
● Pic 7, Ventral (overview). Larva phobetron has reduced legs, moving around by undulations of the body.
● Pic 8, The larva feeding on leaf T. Catappa. Phobetron feeds at any time, day or night. In the the molting period, the larva ceases feeding, getting inactive. Phobetron hás something I don't know how to name the thing is over his head, is like a skin, with a capacity of adhere to the leaf. While the larva eats and sleeps, the 'thing that sticks to', protects the head and prevents the caterpillar can fall leaf.
● Pic 9, The projections are incredible and may vary in number and size. The projections are not stinging. They give strangeness and protection for the caterpillar. The 'tentacles' do not loosen when the caterpillar feels threatened. If a bird trying to peck Phobetron, he can pull the 'tentacles' without hurting the body of the caterpillar. The hairs on the back and the projections are not connected to the interior of the body of the larva, are not vital.
