Euploea klugii
Euploea klugii, the brown king crow or king crow, is a Nymphalid butterfly found in India and Southeast Asia that belongs to the danaid group of the brush-footed butterfly family. The species was first described by Frederic Moore in 1858.

Description

The male forewing is variable in shape, especially in the outline of the termen and dorsum. It is comparatively long in proportion to its width, owing to the lower convexity of the dorsal margin. It has a termen oblique, slightly convex. In the 'novarae' variety it is broad, the great convexity of the dorsal margin making it almost subquadrate, while the termen is more convex than in the typical form. In the female, the difference is less marked.

The typical form on the upper side is a dark brown forewing suffused up to the termen with a blue gloss, a spot at the apex of the cell, a small costal spot, and two short streaks beyond the apex of the cell. In the f two discal spots; in the six subterminal and terminal series of spots; the latter series needed. In both sexes, the subterminal spots are produced inwards. All the spots are bluish white. Hindwing umber brown, the centre glossed with blue; subterminal rows of spots incomplete or obsolescent. The former reduced to two or three spots below the apex, the latter in the male mere dots; in the female absent, only seen by transparency from the underside.

The underside is similar, but paler brown and not glossed with blue. The centre of the forewing is dark, the spots are more clearly defined, subterminal and terminal series are more or less complete. The antennae is black. The head, thorax and abdomen are velvety brown, and the head and thorax speckled with bluish white.

Race kollari: upperside: very dark olive brown, paling to lighter brown towards the termen; both wings with a complete or nearly complete series of subterminal and terminal white spots, the former larger than the latter, in the forewing decreasing in size towards, and curving inwards opposite. The apex; in the hindwing, elongate oval, much larger than the terminal spots, these latter very regular, two in each interspace in the forewing, obsolete towards the apex. The underside is pale olive brown, with the spots as on the upperside, with the addition in the forewing of two to four discal spots, the largest two in the interspace, and a small costal spot; in the hindwing of one or two discal specks. Antennae very dark brown; head, thorax and abdomen dark brown, the former two speckled sparsely with white.
