lycaenid butterfly
Zizula hylax Fabricius 1775

Descriptor: Adult(s)
Description: Photographed on Acanthaceae. Male Upperside: dull violet-blue, which changes to a brighter tint of violet in certain lights. Fore wing: the costa very narrowly, the termen much more broadly dull brown; this edging to the termen in most specimens decreases in width from apex to tornus, and is outwardly followed by an anticiliary darker brown line. Cilia brownish anteriorly, posteriorly brownish at the base with the apical portions white. Hind wing: the ground-colour brighter than on the fore wing, the costal and terminal margins much more narrowly edged with brown, which edging is merged in the anticiliary dark brown line. Cilia: brown along their basal halves, white apically. Underside: grey. Fore wing: a dusky brown lunular line on the discocellulars; two subcostal spots above the cell, one on either side of the discocellular lunule; a very strongly curved discal series of five spots, of which the posterior three are somewhat lunular in shape and placed obliquely en echelon, the next above these hook-shaped, the anterior spot round; both the subcostal spots and the spots of the discal series are black, each narrowly encircled with white; beyond these are inner and outer subterminal dusky lines, which anteriorly are continuous, posteriorly somewhat broken and macular, followed by a very conspicuous jet-black anticiliary slender line. Cilia greyish white, traversed by a medial transverse blackish-brown line. Hind wing: with the following small white-encircled black spots:—a subbasal transverse series of three, followed by a highly curved series of eight spots, that curve across the disc of the wing to the costa and along the latter towards the base; discocellulars with a dusky short lunular line as on the fore wing; terminal markings and cilia similar, but the outer and broader subterminal line more broken and macular than on the fore wing. Antennae black, the shafts ringed with white; head, thorax and abdomen dark brown, with a little violet pubescence on the head and thorax; beneath: palpi, thorax and abdomen greyish white. Female Upperside: glossy brown, without any violet tint whatever; the anticiliary darker brown lines on both fore and hind wings well marked. Underside: very similar to that of the male, the ground-colour a shade darker, the markings slightly larger and more prominent. Antenna, head, thorax and abdomen as in the male, but the latter three without a trace of violet or blue on the upperside.   The Tiny Grass Blue is found in several races throughout tropical and subtropical Africa, Asia, and Oceania, including India, Japan, the Philippines, Singapore, Swaziland, north and east coasts of Australia and also in southern Australia.
