The Canopy Raft in the Masoala National Park (Madagascar). 1. -Towards a Lepidoptera survey. Thanks to the 2001 "Canopy Raft" expedition, many new records can be considered for the Lepidoptera fauna of the Masoala Peninsula, a still poorly investigated region of Madagascar. Moths, butterflies and a few caterpillars were collected over a five week period (mainly in November) in the area of Tampolo, but also near Andranobe, south of Ambanizana. A number of caterpillars have been bred successfully, in particular that of an apparently new her-miniine species (Noctuidae) and the previously unknown larva of Rhagastis lambertoni (Clark) (Sphingidae). Several insect species were obtained from the nests of a possibly new species of Hypsoides (Notodontidae : Thaumetopoeinae). Among them are a Cosmopterigidae and a phycitine Pyralidae, both of which are likely to represent new species. At least 23 species of Bombycoidea (e.g. Hippotion melichari Haxaire -Sphingidae) were caught in october-november 2001 in the Tampolo area. Through a comparison between the efficiency of a light trap put on the canopy raft and that of two similar ones placed under the raft, in rainforest undergrowth, it would seem that most nocturnal hawk-moths tend to fly above canopy level. A checklist of the Sphingidae of Masoala can be proposed for the first time. 65 species of Rhopalocera were indisputably seen (e.g. Smerina manoro (Ward) -Nymphalidae) or collected. Three hesperiids are newly reported for Masoala : Perrotia howa (Mabille), P. silvestralis (Viette) and Borbo ratek (Boisduval).
