Cucius

Cucius is a genus of moths in the family Crambidae. The genus was described by Francis Walker in 1859. The moths in this genus are found in Africa and Asia. They are typically small to medium-sized moths with a wingspan ranging from 15 to 25 millimeters. The forewings are often patterned with intricate designs, which can vary in color from brown and grey to more vibrant hues depending on the species. The hindwings are usually simpler in coloration.

The larvae of Cucius moths are known to feed on various plants, with specific host plants differing among species. Information on the life cycle and specific ecological roles of many Cucius species is limited due to the often inconspicuous nature of these moths and their larval stages. Research into this genus is ongoing, with new species sometimes being identified and described. Identification of Cucius species often relies on detailed examination of wing venation and genitalic structures.
