Freeman’s Metalmark (Calephelis freemani)
Freeman’s Metalmark lived in the Davis Mountains in western Texas. The adult butterflies reached a wingspan of 2 to 2,9 cm, their caterpillars obviously fed on the leaves of the Havana Snakeroot (Ageratina havanensis (Kunth) R. M. King & H. Robinson).
The species was last found in the year 1951 and is considered possibly extinct.
***
Freeman’s Metalmark is very similar to Rawson’s Metalmark (Calephelis rawsoni McAlpine) (see photograph), and both species are often treated as conspecific.
