Caria stillaticia, commonly known as the Gold-headed Metalmark, is a small but striking butterfly in the family Riodinidae. It is notable for its contrasting coloration, with a bright golden-orange head and thorax set against dark brown wings, giving it a distinctive and eye-catching appearance. This species is found in Mexico and Central America, particularly in tropical forests, edges, and clearings. Adults are often seen perching on leaves or flying short distances, and like many metalmarks, they may feed on nectar, sap, or mineral-rich moisture.

Diet

  • Adults feed on flower nectar and are particularly associated with flowering plants in the sunflower family (Asteraceae).

Range

  • Caria stillaticia has a relatively restricted distribution in southwestern and southern Mexico, with its range extending into parts of central and southeastern Mexico.

  • It is occasionally sighted in the Zihua area, particularly where flowering vegetation occurs within dry tropical forest and woodland.

Habitat

  • The Gold-headed Metalmark occurs in tropical deciduous forest, semi-deciduous woodland, thorny vegetation and other warm forest habitats.

  • Males are strongly attracted to damp sand and wet ground, where they gather to obtain dissolved minerals. Females tend to be associated more closely with flowering vegetation.

  • In the Zihua region, look along forest trails, stream margins, damp patches of soil, flowering clearings and edges of tropical deciduous forest.

Description

  • The Gold-headed Metalmark is a small, delicate metalmark, with the intricate reddish-brown and metallic patterning typical of Caria.

  • The wings are predominantly brown with contrasting golden or coppery markings, giving the species its English name.

  • The underside is patterned with fine lines and metallic markings, while the upper surface is darker and more strongly contrasting.

  • Like other Caria, it is a relatively compact butterfly that can be easy to overlook when settled with its wings closed.
