Glaucopsyche melanops, the black-eyed blue, is a butterfly of the family Lycaenidae.

Above similar to the smallest varieties of cyllarus, but the ocelli of the forewing beneath are enlarged, usually much more than in our figure; the row, moreover, is strongly curved and the ocelli gradually increase in size from the first to the fifth, the sixth ocellus, if present, being smaller again.

— In North Africa there occurs a considerably larger form with broader black margin to the forewing and somewhat darker underside; this is algirica Ruhl-Heyne.

[2] The habitat is garrigue, degraded orchards and scrub, hot dry grassfield margins and woodland edge between 100m-800m.

Larval foodplants include Lotus dorycnium, Sulla flexuosa (Hedysarum flexuosum L.).Adults feed on various small composites.
