|(Caligo atreus dionysos)- Owl butterfly|
I found this gorgeous owl butterfly near of the Arenal Volcano, as you can see at the photo it is sucking of the sugar secretion which is coming from the bark of the tree. Owl butterfly is the biggest butterfly of Costa Rica with a forewing lenght 29 - 91mm.
The Natural History:
The eggs are rounded, smooth or ornamented, and the female lays them singly or in groups. The larvae are smooth, with bifid tail, and have a eversible prothoraric gland that produces formic acid in order to repels predator.
The adults feed on decomposing fruit and carrion, besides the genes Caligo is a prest to bananas and African palm, host plants Heliconias, Musaceas, etc.

Enjoy it so much... Michael

a nice natural picture of this Caligo taken from a specific point of view.
Many if not most pictures of Owl Butterflies at TN are taken in butterfly houses.
So, I particularly welcome your picture.
Best wishes, Peter
