| Este trabalho foi realizado na base de extração petrolífera, bacia do Rio Urucu, Coari, Amazonas, nos meses de abril, junho e outubro de 2007. Um total de 16 áreas foram amostradas, 12 delas de clareiras e quatro de florestas, sendo categorizadas em quatro ambientes (clareiras pouco recuperadas, clareiras semi-recuperadas, clareiras bem recuperadas e floresta preservada). Um total de 7.215 califorídeos foram capturados pertencentes a 16 espécies e uma única delas, a Chloroprocta idioidea (Robineau-Desvoidy, 1830), representou 88,06% deste total. Os padrões de abundância da família não diferiram entre os ambientes, porém eles diferiram para as seguintes espécies: Eumesembrinella randa (Walker, 1849), Hemilucilia semidiaphana (Rondani, 1850) e Paralucilia... |

| Diversity of Calliphoridae and Sarcophagidae (Diptera, Oestroidea) in continuous forest and gaps at different stages of regeneration in the Urucu oilfield in western Brazilian Amazonia. The diversity of Calliphoridae and Sarcophagidae in continuous forest and gaps at different stages of regeneration was studied in the Urucu river basin, in Coari, state of Amazonas, Brazil. The flies were collected at 16 sampling points, 12 in gaps at different stages of regeneration (early _ C1, mid- C2 and late successional _ C3) and four in continuous forest _ MT. The diversity of blowflies was similar in the two less regenerated habitats (C1 and C2), and lower than that in the late successional (C3) and continuous forests (MT). By contrast, the diversity of flesh flies... |

| Male Neotropical orchid bees (Euglossini) collect volatile chemicals from floral and non-floral sources and store then in specialized hind tibial structures. The ultimate causes of euglossine fragrance collection remain a mystery. Recent evidence suggests that odoriferous substances play a role in euglossine courtship and serve as indicator of male genetic quality. Males of Eulaema nigrita were observed robbing scents from the detached hind legs of a conspecific male E. nigrita in Belém, Brazil. The hind leg seemed to have been detached during fights between males, since one male was missing a hind leg where the observation was made. This behavior appears to be common among males of E. nigrita since more than one case was observed on the same day. The... |
