wingspan : 80/85 mm
Parides seostris flies from Mexico down to the Amazon basin with various subspecies ; in Ecuador fly two, one East and one West of the Andes (Bollino y Onore 2001).
it is not a mountain butterfly, we only saw it at rio Shankaime, 900 m, at San Isidro and near Mendez.
on one of the pictures you can see a male in a funny position, at an angle of 45° ; it didn't move for about fifteen minutes, and it was not to warm up in the sun as it was on a very hot day ?
