wingspan : 95/105 mm
Caligo illioneus subspecies are seriously questionable, and, to compound the problem, it is quite impossible to tell C. illioneus from C. teucer if you cannot see the upperside of the wings.
this species flies usually at moderate elevations, but on both sides of the Andes.
it is present at Quebrada Cugusha, 1700 meters, and also along rio Shankaime, 900 m and near Macas and Sucúa.
