【 摘 要 】

We carried out a qualitative and quantitative inventory of the hawkmoth fauna (Sphingidae) of an area of semi-deciduous seasonal rainforest in the state of Pernambuco (Tapacurá Ecological Station), northeastern Brazil. Hawkmoths were sampled monthly from October 2004 to February 2007 (27 months). We recorded 31 species from 16 genera, three tribes, and three families. Macroglossinae was the most abundant subfamily and represented ca. 71% of all species. Out of the 277 individuals collected, 88.4% were males. Five new records were made for northeastern Brazil: Enyo gorgon (Cramer, 1777), Perigonia stulta (Herrich-Schäffer, [1854]), Eupyrrhoglossum sagra (Poey, 1832), Nyceryx coffaeae (Walker, 1856) and Xylophanes chiron (Drury, 1773). Eight further species were recorded for the first time for the Pernambuco Endemism Center, showing the important role played by Tapacurá Station in preserving the biodiversity of this insect group. Species richness and abundance were directly related to rainfall: about 70% of all individuals were captured during the rainy season. Changes in Sphingidae populations may, however, be caused by other factors that directly affect either larvae and adults of those insects, such as matrix effect and forest fragment size, which influence migration processes and the presence of predators.
