The adult moths are dark yellow, with a number of dark brown zig-zag lines across each forewing, and a broad black margin to each hindwing. The wingspan is about 2 cms.

    This species shows some variations in the colour and pattern of the forewings which overlap those of other species in Lyclene. The three similar species seem to occur in the following regions:

  • Cyme pyraula - North of Cairns (Queensland)
  • Cyme reticulata - Mossman to Townsville (Queensland)
  • Cyme structa - Maryborough (Queensland) to Mallacoota (Victoria)

    Cyme structa is readily distinguished from the others by the dark margin of the hindwing. Cymereticulata and Cyme pyraula have plain monochromatic hindwings.
