| We sampled Inga Busk species caterpillars weekly in the cerrado on 15 plants of Diospyros burchellii Hern. (Ebenaceae) from January 2002 to December 2003, on 30 plants of Caryocar brasiliense (Caryocaraceae) from July 2003 to June 2004, and since 1991 on several other plant species. In total we found 15 species of Inga on cerrado host plants. Nine species were very rare, with only one to five adults reared. The other six species occurred throughout the year, with higher abundance during the dry season, from May to July, coinciding with overall peaks of caterpillar abundance in the cerrado. Caterpillars of the genus Inga build shelters by tying and lining two mature or old leaves with silk and frass, where they rest and develop (a common habit found in... |

| New World army ants species have an important role in structuring invertebrate communities. Labidus praedator (Fr. Smith, 1858) is a generalist top predator that can reduce pest densities in agroecosystems. The aim of this study was to describe behavioral attributes, diet composition and interspecific interactions of the ant L. praedator. We searched for army ant raids using standardized trail-walk surveys and plotted army ants raids positions on an aerial image. We photographed events at swarm raids of L. praedator and recorded its diet items in basal columns near bivouacs. Six species from four Ecitoninae genera - Labidus (Jurine, 1807), Nomamyrmex (Borgmeier, 1936), Neivamyrmex (Borgmeier, 1940) and Eciton (Latreille, 1804) - were recorded. Caterpillars... |

| O gênero Chlamydastis Meyrick, 1916 (Elachistidae, Stenomatinae) possui 82 espécies descritas da região Neotropical. Chlamydastis smodicopa (Meyrick, 1915) tem local tipo o Estado de Amazonas, Brasil. No cerrado de Brasília, Distrito Federal, as lagartas de C. smodicopa são folívoras externas restritas à planta hospedeira Styrax ferrugineus Nees & Mart. (Styracaceae). De junho de 2000 a junho de 2001, foram vistoriados 243 indivíduos de S. ferrugineus, e encontradas 38 espécies de lagartas de Lepidoptera em 26% das plantas examinadas. C. smodicopa foi a espécie mais comum em S. ferrugineus mas, apesar disso, ocorreu somente em 7% das plantas. As lagartas apresentam no último ínstar cabeça castanho escuro, placa protorácica marron com faixa amarela... |
