257. Curetis bulis bulis (The Bright Sunbeam)

Number: 257
Family: Lycaeniidae
Sub-Family: Curetiinae
Species: Curetis bulis bulis (Westwood, 1852)
Common name(s): The Bright Sunbeam
Photography location: Cuc Phuong N.P. (Ninh Binh Prov.)

The genus Curetis comprises of 18 known species variously distributed from India and Sri Lanka to China, Japan, the Philippines, Malaysia, Sumatra, Borneo, Sulawesi, Papua New Guinea and the Solomon Islands. These butterflies are known as "Sunbeams", due to the brilliant metallic coppery-red uppersides of the males, which glint in the sunshine. Females are earthy brown with large suffused white patches on the upperside, and can easily be mistaken in flight for small Pierids. The undersides of all species are silvery-white with small black dots.

Eight Curetis species are currently known in Vietnam viz. bulis, saronis, santana, tagalica, tonkina, metayei, acuta & dentata (Monastyrskii & Devyatkin, 2016), the first one being the most widespread.
