The pupae of sand flies are 3 mm long and club-shaped. The narrow part is curved and head and thorax are curved backwards. The posterior segments are covered with the exuviae of the fourth-stage larva. With it the pupa is attached to the substrate in a usually vertical position (Perfil'ev, 1968). After approximately 5-10 days the adult emerges.
