- The moonlight's influence on bats activity patterns have been documented for some species. Usually, bats react to increased illumination by reducing the use of open spaces or restricting foraging activity. This study aimed to test lunar cycle influence on frequency of Phyllostomidae bats in three fragments, located in northwestern São Paulo State, analyze the capture rate in the different phases of the cycle and correlate the results with canopy structure of each remaining. This study was based on the on the assumption that the influence of light on the behavior of bats is lower in shaded areas. The decrease in species richness in relation to the moon phase was significant in the least shaded area. In environments with more closed canopy, the rate of capture of bats was homogeneous along the four phases of the moon. The results indicated that local wealth cannot be sampled effectively if the catches are restricted to any period of the lunar cycle for fruit and nectar, and in more shaded environments the effects of lunar phobia is apparently null.
