Summary: | The monitoring Lepidoptera populations provides important information to assess the dynamics and ecological changes in ecosystems. In this work, it was evaluated and characterized the Lepidoptera fauna of forest fragment of the IFSULDEMINAS--Campus Muzambinho, MG state. Throughout 12 months, 590 Individuals of 69 species belonging to 10 families were captured. The most abundant family was Nymphalidae (73.56% of subjects). The most abundant species were Godartiana muscosa, Mechanitis lysimnia, Hermeuptychia sp and Mechanitis polymnia casabranca, which are bio- indicators of disturbed and/or urban environments. On the other hand, it was found rare species, such as Notascea brevispula. Different species were constant and others occurred in only a short period of the year. The diversity and abundance were higher in hot and rainy months. The diversity index Shannon- Wiener and Simpsom indicate a median diversity and equitability index point absence of dominance. Keywords: environmental monitoring; Atlantic forest; lepidoptera; bioindicators. O monitoramento de populacoes de Lepidoptera fornece informacoes importantes para avaliar a dinamica e as mudancas ecologicas nos ecossistemas. Neste trabalho avaliou-se e caracterizou-se a Lepidofauna da mata do IFSULDEMINAS--Campus Muzambinho--MG, estabelecendo um padrao para inumeros fragmentos semelhantes na regiao. Em 12 meses de levantamento foram capturados 590 individuos de 69 especies, distribuidas em 10 familias. A familia mais abundante foi Nymphalidae (73,56% dos individuos). As especies mais abundantes foram Godartiana muscosa, Mechanitis lysimnia, Hermeuptychia sp e Mechanitis polymnia casabranca, que sao bioindicadoras de ambiente perturbado e/ou urbano. Em contrapartida, foram encontradas especies raras, tais como Notascea brevispula. Diferentes especies foram constantes e outras ocorreram em apenas um curto periodo do ano. A diversidade e abundancia foram maiores nos meses quentes e chuvosos. Os indices de diversidade de Shannon- Wiener e Simpson indicam uma diversidade mediana e o indice de Equitabilidade aponta ausencia de dominancia. Palavras-chave: monitoramento ambiental; mata atlantica; lepidoptera; bioindicadores. |
