Opogona is a genus of the fungus moth family, Tineidae. Therein, it belongs to the subfamily Hieroxestinae. As it includes Opogona omoscopa, the type species of the now-abolished genus Hieroxestis, it is the type genus of its subfamily. Thes are most common in the tropical parts of the world; for example, from Australia, almost 30 species are known. But two members of this genus – the banana moth (O. sacchari) and to a lesser extent O. omoscopa – have been introduced even to Europe.
