Curetis bulis, the bright sunbeam, is a species of butterfly belong to the lycaenid family. It is found in Asia.
Male upperside, forewing: velvety black, an elongate broad medial patch dark orange red, that extends from base outwards for about three-fourths the length of the wing and fills the area from vein 1 to the middle of the cell; in some specimens diffusely, spread below vein 1 near base, but there shaded with dusky black; the outer margin of this red patch unevenly rounded. Hindwing: brownish black, a large orange-red spot above vein 3 to near apex, inwardly extended into the cell to near the base of the wing and posteriorly diffuse below vein 3, but in the cell thickly overlaid with dusky-black scaling and posteriorly shaded with long brown hairs that in certain lights take a golden tint; above the cell extended from the base of the wing to the inner margin of the orange spot is a prominent broad streak of a shade darker than the ground colour; abdominal fold pale pinkish brown. Underside: silvery white with sparsely scattered minute black dots. Forewing: a discal and inner subterminal series of very indistinct somewhat lunular black markings that form broken anteriorly convergent bands, which are continued over the hindwing to the tornus; beyond these, on both forewings and hindwings, succeeds an outer subterminal series of minute black dots, in most specimens very indistinct. Antennae, head, thorax and abdomen dark brown; sides of the abdomen golden brown; beneath: palpi, thorax and abdomen white.
Female upperside: more or less as in the male, but the dark orange-red medial patches replaced by white and much larger. On the forewing this white patch extends above the cell, the discocellulars closing which are prominently marked by a black tooth, and posteriorly it reaches the dorsal margin. On the hindwing the white patch is very large and in some specimens very diffuse. Both forewings and hindwings are shaded at the base by dusky scales and in many specimens the markings of the underside are plainly visible by transparency; the broad black streak above the cell on the hindwing is present in some, absent in other specimens. Underside: ground colour and markings as in the male, but much more prominent.
Upperside golden or coppery orange o£ a shade paler than the orange patch in the typical form. Forewing: costal margin broadly black, the width of the black colour increasing to the apex and continued from below that in an even border along the termen to the tornus, thence along the apical third of the dorsum, ending more or less diffusely in a point; discocellulars marked by a prominent tooth extended from the black costal border. Hindwing: base and dorsal area lightly irrorated (sprinkled) with fuscous scales, the latter also shaded with long pale brown hairs; termen with a blackish border of varying width but generally widest in the middle, its inner margin more or less diffuse; costal margin broadly pale yellow. Underside: silvery white; markings similar to but in some specimens even more indistinct than in bulis. Antennae, head and thorax of a paler brown than in bulis; sides of the abdomen golden yellow; beneath: palpi, thorax and abdomen white.
