Anthophagy in the leaf beetles (Coleoptera, Chrysomelidae)

Laboratory experiments were performed on leaf beetles collected on flowers. Flower consumption (anthophagy) was demonstrated for adults of Donacia bicolora, D. brevitarsis, D. obscura, D. thalassina, Plateumaris discolor, Cryptocephalus laetus, C. sericeus, C. solivagus, Labidostomis longimana, Hydrothassa marginella, Phaedon concinnus, Galerucella nymphaeae, Neocrepidodera femorata, Altica oleracea, Aphthona lutescens, Longitarsus pellucidus, and larvae of Entomoscelis adonidis, H. marginella, and G. nymphaeae for the first time for all the species except for P. discolor, L. longimana, and C. sericeus. The feeding behavior was described, and the mouthparts of adults were studied. The mandibles and maxillae of the Donacia, Plateumaris, and Orsodacne species mentioned are adapted to consuming pollen. Some questions of ecology and evolution of anthophagy are discussed. An overview of literature on anthophagy in the leaf beetles is presented. © 2010 Pleiades Publishing, Ltd.
