Dyson's Blue Doctor

Rethus dysonii


A beautiful Riodinidae butterfly, one of the 3 Rethus species. This one is found at higher altitudes than the other 2. The males are usually seen imbibing minerals along the sides of ditches and small streams. They are often quite placid when doing this, and allow one to get quite close. They are seen more frequently in cloudy conditions.


Mud-puddling on a bridge over a small stream. In the eastern Andes the altitudinal range is from about 800-2000m.
