According to our observations at Ishigaki-island, Loochoo, in August 1965, this lycaenid usualy lays eggs on the flower bud or bud stalk of host plant, Derris uliginosa BENTHAM (Leguminosae). Strange to say, the eggs are always enveloped in the secretion of frothy material which, just after secretion, resembles that of spitlle bugs, but coagulates after about twenty-five minutes. The number of laid egg is counted through frothy covering. Among 33 eggs counted in total, 2 are laid singly and the rest in 13 groups, 1, 3 and 9 groups containing 4, 3 and 2 eggs, respectively. The newly hatched larva eats its way out of egg-shell and dried frothy covering and burrows into a bud as do the caterpillar of Lampides boeticus.
