They feed on stems and leaves of Hibiscus spp., Malva spp., Sida spp., Althea rosea (Hollyhock), Malvastrum fasciculatum, and other plants in the family Malvaceae. Adults and immature forms are quite gregarious on stems, leaves and roots. Known distribution includes Mexico, El Salvador, Texas, Florida and Hawaii.
