The mark-recapture of bats allows individualization and thus aspects inherent to the individual can be studied. This study aimed to discuss the importance of marking bats in Brazil, where few studies report the marking of individuals captured and the recaptures. With the use of marking with plastic collar and through compilation of data was analyzed three topics related to mark-recapture bat Phyllostomidae: variation of recaptures in localities in the State of Rio de Janeiro, records of movements in Brazil, variations in the abundance of ectoparasitic Streblidae in individuals of Carollia perspicillata. The Gip?ia Island, Marambaia Island and Itacuru?? Island and three localities on the continent, State Ecological Station Para?so, Morro de S?o Jo?o and Rio das Pedras Reserve had reported recapture rates. The rates of recapture of the islands were significantly higher than the continent, islands can be shown that good places to recapture studies of bats. In the six localities were marked from 487 to 1318, with 24 to 158 recaptures, ranging from three to 11 species by locality. Recapture rates varied by location from 4.2 to 19.2%. Carollia perspicillata was the only species recaptured in six places and had the highest rates of recaptures in the Itacuru?? Island with 43.5%.Were reported movements of Glossophaga soricina of 6.2 km in the municipality of Serop?dica, of Artibeus lituratus between the Grande Island, municipality of Angra dos Reis, and Prainha, in the municipality of Rio de Janeiro, a linear distance of 71 km. Twenty-seven movements realized between seven points of Marambaia Island, municipality of Mangaratiba, of six species, Anoura caudifer, Artibeus fimbriatus, Artibeus planirostri, Artibeus obscurus, Carollia perspicillata e Platyrrhinus lineatus, with movements to 2.4 km. With the analysis of records of Phyllostomidae movement throughout Brazil observed a high number of records of Artibeus lituratus, with this species showing the greatest distances to travel, contributing to a positive linear correlation between the distance of movement and body size. Through individualization was possible to determine the variations in the abundance of Streblidae ectoparasite in 42 individuals of C. perspicillata. The long time past between capture and recapture did not increase the number of parasites found. Individuals who had more ectoparasites at the moment of capture did not have more Streblidae at the moment of recapture. Only two individuals showed significant differences in the abundance of Streblidae between capture and recapture. The more effort of marking will contribute to a greater number of recaptures, allowing various analyses that will contribute to the understanding of the biology of bats.
