Cinnabar Devil was named after the Red Devil cinnabar mine, a primary source of mercury. It has been found in Dominica near its sulfur springs at the southern end of the island along the west coast. Cinnabar is still being deposited at the present day, such as from the hot waters of Sulphur Bank Mine in California and Steamboat Springs, Nevada.

Females can lay up to 300 eggs, usually in batches of 30 to 60 on the underside of ragwort leaves.
