ESTUDO DA DIVERSIDADE DE BORBOLETAS (LEPIDOPTERA: RHOPALOCERA) EM DUAS LOCALIDADES NO MUNICÍPIO DE FREDERICO WESTPHALEN, RIO GRANDE DO SUL, BRASIL. / STUDY OF THE DIVERSITY OF BUTTERFLIES (LEPIDOPTERA, RHOPALOCERA) IN TWO LOCALITIES IN THE FREDERICO WESTPHALEN CITY, RS, BRAZIL.Giovenardi, Ricardo 22 March 2007 (has links)
Contributing to the butterflies diversity knowledge from Estacional Decidual Forest of Rio Grande do Sul State, a systematic survey was carried out in two localities of the Municipal District of Frederico Westphalen: Villa Faguense Municipal Park and Schöenstatt Sanctuary, from March 2005 to April 2006. In 140 hours of sampling, were registered 3129 individuals distributed in 174 species. Of the sampled species, 56,32% belong to the Nymphalidae family
(12 subfamilies), 19,54% to Hesperiidae (2 subfamilies), 6,32% to Papilionidae (1 subfamily), 8,05% to Pieridae (3 subfamilies), 6,32% to Lycaenidae (2 subfamilies) and 3,45% to Riodinidae (1 subfamily). Ten species sampled were still no published for the State: Euptoieta hegesia (Cramer, 1779), Dynamine athemon (Linnaeus, 1758), Myscelia orsis (Drury, 1782), Pareuptychia summandosa (Gosse, 1880), Taygetis laches marginata (Staudinger, 1887), Yphthichoides castrensis (Schaus, 1902), Caligo eurilochus brasiliensis (Felder, 1826), Urbanus doryssus albicuspis (Herrich-Schaffer, 1869), Eurybia pergaea (Geyer, 1832), Lemonias zygia (Hübner, 1807). The Shannon-Wiener diversity index was higher in Villa Faguense Municipal Park, place less disturbed, and smaller in Schöenstatt Sanctuary. The Simpson and Berger-Parker dominance indexes had been more representative in Schöenstatt Sanctuary, with higher number of abundant species, and less representative in Villa Faguense
Municipal Park. Among the species captured 131 (75.29%) are accidental, 25 (14.37%) are accessory and 18 (10.34%) are constant species. / Contribuindo para o levantamento sistemático e o conhecimento de borboletas da Floresta Estacional Decidual de Frederico Westphalen, foram realizadas saídas de campo mensais em duas localidades no Município, entre março de 2005 e abril de 2006. Em um total de 140 horas de amostragem, foram registrados 3129 indivíduos distribuídos em 174 espécies. Destas, 56,32% das espécies pertencem à família Nymphalidae (12 subfamílias), 19,54% Hesperiidae (2 subfamílias), 6,32% Papilionidae (1 subfamília), 8,05% Pieridae (3 subfamílias), 6,32% Lycaenidae (2 subfamílias) e 3,45% Riodinidae (1 subfamília). Foram registradas 10 espécies de borboletas ainda não publicadas para o Estado: Euptoieta hegesia (Cramer, 1779), Dynamine athemon (Linnaeus, 1758), Myscelia orsis (Drury, 1782), Pareuptychia summandosa (Gosse, 1880), Taygetis laches marginata (Staudinger, 1887),
Yphthichoides castrensis (Schaus, 1902), Caligo eurilochus brasiliensis (Felder, 1826), Urbanus doryssus albicuspis (Herrich-Schaffer, 1869), Eurybia pergaea (Geyer, 1832),
Lemonias zygia (Hübner, 1807). O ìndice de Diversidade de Shannon-Wiener foi maior no Parque Municipal da Vila Faguense, local menos perturbado, e menor no Santuário de
Schöenstatt. Os índices de dominância de Simpson e Berger-Parker, por sua vez, foram mais representativos no Santuário de Schöenstatt, com maior número de espécies abundantes, e
menos representativos no Parque Municipal da Vila Faguense. Foram registradas em Frederico Westphalen 131 (75,29%) espécies acidentais, 25 (14,37%) espécies acessórias e 18
(10,34%) espécies constantes.
