WHITE SAILOR

White Sailor, DYNAMINE THESEUS

Above you can see the latest addition to our Butterflies of Yucatán Identification Page at ../yucatan/mariposa/

Usually that's known as the White Sailor. It's DYNAMINE THESEUS, distributed from southern Mexico south through Central America to northern South America, and despite occurring over such a large area not much is known about it or its caterpillars.

The "Sailor" part of the English name applies to a fair number of species in the genus Dynamine. This is the first White Sailor I've spotted, but the Mexican Sailor, Dynamine posterta, is common here, in some disturbed environments the most evident of all species. You might enjoy comparing this week's White Sailor with the common Mexican Sailor, at www.backyardnature.net/yucatan/mariposa/butt005.jpg

Our local form of the Mexican Sailor is bluish above, as shown at www.backyardnature.net/yucatan/mariposa/butt006.jpg
