The Small Jewel Blue (Plebejus christophi)[1] is a small butterfly found in Asia[2][3] that belongs to the Lycaenids or Blues family.

Description

The Small Jewel Blue is 28-35mm in size. The male butterfly is rather dull violet-blue above with narrow borders. The female is brown above and has blue-scaled bases. On the underside of both sexes, the hindwing sport small metallic spots along the entire margin but without prominent red marginal spots. The marginal spots on the margins of both the forewings and hindwings are faintly orange-crowned. The discal spots on the hindwing are small or minute while those on the forewing may be large and prominent.[4]

Description ex Bingham

Race samudra, Moore. Male Upperside: pale lavender-blue. Fore and hind wings: termen somewhat broadly and diffusely fuscous black; costal margin and apex of hind wing more broadly so; in fresh specimens the bluish scaling on the hind wing posteriorly is carried nearly to the terminal margin, this gives the wing an appearance of a posterior terminal series of three or four large fuscous black spots, one in each interspace; cilia white. Underside: pale grey. Fore wing with the usual transverse disco-cellular and discal series of six while-encircled black spots, no spot in the cell or in interspace 1; the discal row of spots regular (not sinuate), slightly curved, very obliquely placed, sloping posteriorly inwards, the four posterior spots in the series large and posited en echelon; these are followed by a double subterminal series of dusky lunules and a slender anticiliary black line; the series of Innules become in many specimens obsolescent anteriorly. Hind wing: the markings much as in the female of L. balucha, but the discal scries oF spots is placed further inwards,the spots of the subterminal row are speckled with minute metallic green scales, and the ochra-ceous edging to the transverse series of black lunules is wanting.[5]

Female upperside brown, the bases of the wings irrorated with bluish-grey scales, the irroration extended irregularly along the dorsal margin of the hind wing. Cilia of fore and hind wings conspicuously white. Underside; ground-colour as in the male; markings slightly larger, more clearly defined. Fore wing: the transverse diseal series of spots insinuate, the posterior three spots of the series distinctly larger than the others, the middle spot of these three shifted inwards ; the terminal markings consist of a transverse postdiscal series of black lunules edged outwardly with bright ochraceous, followed by a transverse series of black spots and an anticiliary black line, all very clearly defined. Hind wing: markings very similar to those of the male but the discal series of spots is closer to the base of tho wing and the postdiscal transverse row of black lunules is prominently edged outwardly with ochraceous. In both sexes the antennae are black, the shafts ringed as usual with white; tho head, thorax and abdomen are dark brown or black with a more or less dense clothing of purplish-blue hairs and scales; beneath: the palpi, thorax and abdomen white.[5]
