Abstract


The first natural history account of Discomorpha (Discomorpha) biplagiata (Guérin) (Chrysomelidae: Cassidinae: Omocerini) from Ecuador is presented. Larvae and adults feed on the leaves and stems of Cordia hebeclada Johnst. (Boraginaceae), the fi rst documented host plant for the species. Oviposition and pupation also occur on this host. Young larvae suffered heavy predation, especially from Ectatomma sp. (Formicidae: Ponerinae) and Oplomus nr. marginalis (Pentatomidae: Asopinae).
