SMITH Smithsonian Tropical Research Institute, Unit 0948, APO AA34002-0948 U.S.A. ABSTRACT. Larval and adult food plant records for the moth subfamily Uraniinae (sensu Sick 1937) are reviewed. Reliable larval food plant records for all seven genera include only the genera Omphalea L., Endospermum Benth., and Suregada Roxb. ex Rottl. (Euphorbiaceae), and this specialization on Euphorbiaceae supports Sick's concept of Uraniinae (based on meta thoracic and tympanal morphology) as a monophyletic group. Whereas Omphalea is known to be fed on only by larvae of the three strictly day-flying genera (Urania Fabricius, Chrysiridia Hiibner, and Alcides Hiibner), Endospermum is a recorded foodplant for Alcides and three primarily nocturnal genera (Lyssa Hiibner, Urapteroides Moore, and Cyphura Warren). The latter two genera have been traditionally included in the Microniinae, as has been Urapteritra Viette, whose larval food plant Suregada is reported here for the first time. Some ecological and evolutionary aspects of uraniine larval foodplant specialization are discussed. A putative phylogeny of Uraniinae based on published hearing organ and larval morphology is presented, and the phylo genetic significance of larval foodplant relationships evaluated. Adult foodplants (nectar resources) for the diurnal uraniines are summarized, and the possibility of their role in the moths' reproductive or predator defense ecology is briefly discussed. Additional key words: Microniinae, Omphalea, Endospermum, Suregada, Euphor biaceae.
