A heterogeneidade de habitat e o clima estacional tendem a causar padr?es de atividade dos organismos e de diversidade de esp?cies. Por?m, esses padr?es sazonais e espaciais em comunidades de borboletas em ambientes secos ainda n?o s?o claros. Estudamos uma comunidade de borboletas frug?voras na ESEC Serid?, no nordeste do Brasil, com o intuito de caracterizar a guilda no semi?rido e verificar a contribui??o relativa de vari?veis clim?ticas e vegetacionais sobre a sua composi??o, diversidade e fenofaun?stica. As borboletas foram amostradas mensalmente, durante um ano, e a distribui??o das esp?cies foi associada ?s caracter?sticas estruturais de tr?s fitofisionomias (ex. riqueza e abund?ncia de esp?cies arb?reo-arbustivas, cobertura de dossel, cobertura de herb?ceas, serapilheira) e a dados climatol?gicos (temperatura, pluviosidade e umidade). Foram capturados 9580 indiv?duos de 16 esp?cies de borboletas, pertencentes a quatro subfam?lias (Biblidinae, Charaxinae, Nymphalinae e Satyrinae). A riqueza, abund?ncia e diversidade variaram em diferentes escalas, principalmente no tempo, sendo maiores na esta??o chuvosa, enquanto a ?-diversidade e turnover foram maiores na seca. A distribui??o das esp?cies seguiu principalmente as mudan?as de umidade, pluviosidade e fenologia vegetacional, n?o havendo limites definidos entre habitats. O per?odo de voo foi compartilhado dentro das subfam?lias, as quais devem ter resposta distinta aos est?mulos ambientais, como tamb?m responder ? fenologia de plantas hospedeiras e ter estrat?gias de reprodu??o distintas. Havendo inclusive, ind?cios de adapta??es fisiol?gicas e comportamentais como reprodu??o sazonal e estiva??o. Portanto, houve controle ambiental sobre a distribui??o e diversidade de esp?cies, com o papel chave da associa??o do clima e estrutura da vegeta??o na diferencia??o da comunidade em esta??es do ano, e da disponibilidade e qualidade de recursos sobre a varia??o de abund?ncia das esp?cies, em pequenas escalas. Tais resultados podem dar suporte ao biomonitoramento e conserva??o de ?reas preservadas, sobretudo em ambientes sob press?o antr?pica e de condi??es ambientais extremas como o semi?rido. / The spatial and temporal distribution of the population reflects the adjustment of their biological characteristics to environmental conditions and biotic interactions as adaptive and phylogenetic precursors elements. The habitat?s heterogeneity and alternating seasons tend to cause patterns of activity of organisms and species diversity. However, these seasonal and spatial patterns in butterfly communities in dry environments are not yet clear. We studied a community of frugivorous butterflies in ESEC Serid?, in northeastern Brazil, aiming to characterize the guild in semiarid and check the relative contribution of climate and vegetation variables on its composition, diversity and phenofaunistic. The butterflies were sampled monthly during one year, and the distribution of species was associated with structural characteristics of three vegetation types (eg. richness and abundance of tree and shrub species, canopy cover, herbaceous cover, litter) and climatological data (temperature, rainfall and humidity). We captured 9580 individuals of 16 species of butterflies belonging to four subfamilies (Biblidinae, Charaxinae, Nymphalinae and Satyrinae). The richness, abundance and diversity varied in different scales, especially in time, being higher in the rainy season, while the ?-diversity and turnover was higher in the dry. The distribution of species mainly followed the changes in humidity, rainfall and vegetation phenology, with no defined boundaries between habitats. The flight period was shared within subfamilies, which should have distinct response to environmental stimuli, as well as respond to the phenology of host plants and have different reproductive strategies. There is even evidence of physiological and behavioral adaptations as seasonal reproduction and aestivation. So there was environmental control over the distribution and diversity of species, with the key role climate Association and vegetation structure in the community of differentiation in the seasons, and the availability and quality of resources on the variation of species abundance in small scales. These results may support the biomonitoring and conservation preserved areas, particularly in environments under human pressure and extreme environmental conditions such as semi-arid.
