Coleophora achilleae is a moth of the Coleophoridae family that is endemic to Greece. The larvae feed on Achillea umbellata. They mine the leaves of their host plant. They create a smooth, trivalved, tubular silken case of about 8 millimetres (0.31 in) with a mouth angle of about 20°. It is off-white to light brown in color. The oldest part of the case is warty and includes parts of the plant epidermis.
