Ruellias are popular ornamental plants. Some are used as medicinal plants, but many are known or suspected to be poisonous. Their leaves are food for the caterpillars of several Lepidoptera [butterflies and moths], typically Nymphalinae and in particular members of their tribe Junoniini. Nymphalinae using Ruellia as host plants include the Common Buckeye [Junonia coenia], recorded on Ruellia nodiflora, the Lemon Pansy [Junonia lemonias], recorded on Ruellia tuberosa, and the Malachite Butterfly [Siproeta stelenes] and Australian Lurcher [Yoma sabina], which are recorded on several species.
