Monodontides musina, the Swinhoe's hedge blue, is a butterfly of the family Lycaenidae. It is found in South-East Asia, including India.
Male underside: pale lilacine grey. Forewing: costa bordered by a slender line, termen by a comparatively broad and even band of dusky black, the latter diffuse along its inner margin. Hindwing: costal margin diffusely dusky black, termen with a slender black anteciliary line; dorsal margin narrowly pale. Underside: white with a slight tinge of blue. Forewing: a short line on the discocellulars, a postdiscal transverse series of six abbreviated lines pointing obliquely outwards and en echelon one with the other, the uppermost shifted well inwards, followed by a subterminal series of transverse spots enclosed between an inner subterminal, lunular, transverse line and an outer anteciliary slender line, pale brown. Hindwing: a transverse subbasal series of three, sometimes four, minute spots and a spot beyond on the dorsum, with a larger subcostal spot near the apex of the wing, black; a short slender line on the discocellulars and some irregular dots on the disc pale brown; terminal markings as on the forewing. Cilia of both forewings and hindwings whitish. Antenna, head, thorax and abdomen dark brown, the antennae ringed with white beneath: the palpi, thorax and abdomen white.
Female upperside, forewing: a broad border to the costal and terminal margins dusky black, the rest of the wing iridescent light blue; on the costa the lower edge of the black traverses the middle of the cell, on the apex and termen it occupies the outer fourth of the wing. Hindwing: anterior third dusky black, the rest of the wing pale lilacine glossed with iridescent blue in certain lights; a subterminal series of dusky black spots that more or less coalesces with an anteciliary dusky black hue and is enclosed on the inner side by a slender similarly-coloured lunular line. The underside, antennae, head, thorax and abdomen as in the male.
The butterfly was earlier known as Lycaenopsis musina Swinhoe.
