ONE PLANT, TWO HERBIVORE STRATEGIES: LEMA INSULARIS (CHRYSOMELIDAE: CRIOCERINAE) AND ACORDULOCERIDEA COMPRESSICORNIS (PERGIDAE: ACORDULOCERINAE) ON DIOSCOREA MEXICANA (DIOSCOREACEAE), WITH OBSERVATIONS ON A LEMA CO-MIMIC

Abstract The apparently aposematic immature stages of a tropical shining leaf beetle, Lema insularis, are described, the host plant is revealed to be Dioscorea mexicana, and observations on the camouflaged larvae of a co-existing herbivore, the sawfly Acorduloceridea compressicornis, and the adults of a co-mimic, Diabrotica godmani, are made.
