Two chaetae on the ventral side of Ant.3 and one on Ant.2 are modified as thin, wavy macrochaetae. Male spurs (common in many species of the subfamily) also are present, set on all antennal segments. Sens and basal microsens keep their normal arrangement and number. Subadult males (males of the same size as adults but with closed genital orifice) principally have the same shape of head and antennae but are devoid of "male" macrochaetae on body and of stout chaetae on antennae and head. Populations from Shanghai consist of smaller (ca 1.7 mm) and non-reproductive individuals. Immature males are also slightly affected by having thicker and slightly bent antennae (
