It is the second largest family of butterflies after Nimphalidae, with over 5,000 species worldwide.
They constitute about 30% of the known species of butterflies.
The adults are small, usually under five inches, and brightly colored, sometimes with a metallic sheen.
The larvae are often flattened rather than cylindrical, with glands that produce secretions that attract ants and submit in order to be cured,
nourished and protected from any parasites or predators. The Lycaenidae are different in their eating habits and,
excluding the specimens phytophages, some of them are entomophagous feed on aphids, scale insects and ant larvae.
