This group appears to form a connecting link between the Nymphalidae on the one hand, and the Lycaenidae on the other. Family 3. The Blues. LYCAENIDAE. The “blues,” “coppers,” or “hair-streaks” are so named on account of their rich colourations or wavy markings on the under side of the wings. Though often passed over by the ordinary collector because of their small size, they are much sought after by lepidopterists for their beauty and bright metallic tints. Their bodies are slender, and the wings somewhat fragile; though they can fly well, they usually prefer to flit about the bushes and sheltered gullies, and when they settle have the habit of folding their wings in an erect position above the body, so that unless disturbed they are not very noticeable. The prevailing colours are metallic blue, or coppery red, with eyes upon the wings in some groups, while others are ornamented with dainty feathery tails, or lobes upon the hind wings. The colours and markings of the sexes often differ in the same species on the upper surface, but always correspond on the under-side. The legs are more developed than in the Nymphalidae, the tarsi of the male somewhat aborted, but that of the female complete. The larvae are curious, short, slug-like, greasy grubs, dull brown or green; some of them are gregarious, clinging to the twigs by day and feeding at night. The pupae are attached to the twig by the tip of the abdomen and girthed with a silken thread round the middle.
