The wattle bagworm (Kotochalia junodi, formerly Acanthopsyche junodi) is a species of moth in the family Psychidae. In southern Africa it is a pest of the black wattle (Acacia mearnsii) which is grown largely as a source of vegetable tannin. Kotochalia junodi is indigenous to Southern Africa, where it originally fed on indigenous relatives of the wattle. Like all members of the family Psychidae, the male larva develops into an adult in a mobile silken bag covered with materials such as thorns and twigs. Only once it is mature does it leave the bag to mate. The female never leaves her bag.
