The lime blue is a small, fast-flying blue with only slight differences between the sexes; the upperside is bluish purple with a narrow dark border in males and a wider one in females, while the underside is pale grey and white with a dense pattern of small dark brown spots edged in white.
Caterpillars feed on the young leaves of citrus trees and related plants and are pale green throughout their instars, matching their host leaves closely, and several generations can be produced through the year wherever citrus grows in gardens, scrubland or forest edges.
