Taxonomia de Hedylidae (Lepidoptera, Hedyloidea) da Amazônia Brasileira e aspectos biológicos de Macrosoma Tipulata Hubner, 1818

Abstract

The Hedylidae of the Brazilian Amazon were inventoried along with the morphological characterization of the species. Specimens were obtained from Brazilian entomological collections along with 165 adults collected during this study. A total of 15 species and 285 specimens were studied including one new species and two new distribution records for the Brazilian Amazon: M. tipulata, M. hyacinthina, M. heliconiaria, M. semiermis, M. hedylaria, M. conifera, M. stabilinota, M. nigrimacula, M. klagesi, M. muscerdata, M. lucivittata, M. bahiata, M. Iamellifera, M. ustrinaria e Macrosoma sp.. The female of M. klagesi, which was unknown, is described and its genitalia illustrated. Biological and behavioral aspects of Macrosoma tipulata Hubner 181 8 were studied under greenhouse conditions. Considering the width of the cephalic capsules, five instars were determined with a mean growth rate of 1.48. The larva1 development period took, in average, 18.1 12.3 days: the duration of the first instar was 2.210.4 days; the second instar 3.110.4 days; the third instar 3.710.5 days; the fourth instar lasted 4.310.5 days; and the fifth instar 4.9rt0.5 days. The prepupa lasted 1.65k0.23 days with a viability of 95%. The pupal stage was 5.710.5 days for males and 5.9k0.5 for females with viability of 91% e 93%, respectively. Of the eggs which were reared, 12 larvae emerged in 5 or 6 days with a viability of 98%. Ernergence occurred between 18:00 and 20:OO hours. The mean adult life span was 5.212.2 days for males and 4.811.2 days for females. The sex ratio was 0.47. Evaluation of the behavior of M. tipulata in greenhouse conditions yielded nocturnal habits.
