The adult female moths of this species have grey forewings with variable patterns, including two incomplete dark lines across each one. The hindwings are plain grey with a vestigial pattern. The females have threadlike antennae.
The males have the dark brown bands embedded in a more complex pattern. The males have antennae with a feather-like fringe on one side. Both sexes have a dark irregular spot with a pale centre near the middle of each forewing. The moths normally rest with the forewings covering the hindwings. The wingspan is about 2 cms.

The name Dichromodes mesogonia appears to be applied to a number of similar species. In due course they will probably be described separately, and be given separate names.
