At Neotropics are registered 5 subspecies Caligo eurilochus (Lamas, 2004). This species is really prominent in the group of insects, by gigantic size. Spends much time resting on the trunks of the understory and has greater activity during crepuscular hours.

 The caterpillars live gregariously on plants of Marantaceae,  Musaceae and another families.This group is created very easily in artificial conditions, and often can quickly increase the population (Otero & Marigo, 1990). They are easy to maintain in butterfly-house and arouse much interest when showing his big eyes in the  wings.
