Ithomeis is a butterfly genus in the butterfly family Riodinidae present only in the Neotropical ecozone.

Species

  • Ithomeis aurantiaca Bates, 1862 present in Guyana, Brazil, Colombia, Venezuela, Ecuador and Peru
  • Ithomeis eulema Hewitson, 1870 present in Costa Rica, Panama, Venezuela and Colombia
  • Biology

    Both species are mimics. The pattern of black, orange and large translucent areas found in Ithomeis is shared by toxic genera from the Ithomiinae (examples are Ithomia and Oleria) and a number of toxic Arctiidae. The pattern is also shared with several other Riodinidae genera (examples are Stalachtis, Ithomiola and Brachyglenis) which may be part of mimicry rings.

    Ithomeis aurantiaca has several subspecies, some are very different in appearance and were formerly regarded as full species. I. a. satellites and I. a. astrea closely resemble species of Heliconius. Other subspecies include I. a. mimica and I a. stalachtina, which have extensive orange markings and much reduced hyaline areas and these mimic toxic Ithomiines in the genera Pseudoscada, Hyposcada and Hypoleria. The different subspecies mimic models which share their distribution.

    The habitat is tropical forest including cloud forest at 800-1500 m. The eggs are pink, and laid in clusters of between 40 and 50 on the upperside of leaves. The larval food plant is Heisteria.
