Mona ground iguanas eat the caterpillar of sphingid moths. Sphingid larvae tend to be specific feeders, rather than generalists. Sphingid caterpillars are medium to large in size, with stout bodies. Sphingid moths feed on the nectar of "J. integrifolia". The usual sphingid horn is absent, and in its place there is a double wart. Hippotion rosetta, or Swinhoe's striated hawkmoth, is a sphingid moth of the family Sphingidae.
