Caligo eurilochus

Profile Caligo Eurilochus

Otherwise known as the Forest Giant Owl, (Caligo eurilochus) is an owl butterfly, ranging from Mexico, through Central America, to the Amazon River basin in South America.

The larvae feed on several hostplants, including Calathea latifolia (Marantaceae), Heychium sp. (Zingiberaceae), Heliconia latispatha (Heliconiaceae), and Musa spp. (Musaceae). The larva also feed on the fruit of most Musa species. The female lays a large number of eggs of one of the host plants and the small larvae hatch after about 3 to 5 days. Fertile eggs develop a grey ring just above the center. Infertile eggs collapse. The first instar of the larvae are white with two orange/brown stripes down the length of their body leading to two little spindles at the end. Later on in life the larvae develop hairs mimicking spines and a crown made of four horns at the back of their head. The larvae then find a high enough spot to pupate and begin the change of metamorphosis. The large owl butterfly emerges and begins to pump out its wings, later searching for food. the butterflies drink the juices of fermenting fruits and a wide variety of nectar plants.
