Most chironomidlarvae have well developed, multi-segmented antennae placed anterdorsally on the upper genae. The antenna typically is strongly sexually dimorphic: males have a prominent, generally plumose antenna comprising a narrow scape, globular pedicel and a number (usually 11-14) of cylindrical flagellomeres, but the antenna may resemble that of the female. The antenna of most females has a smaller pedicel, lacks any plume and often has fewer, more flask-shaped flagellomeres.
