【 摘 要 】

http://dx.doi.org/10.5007/2175-7925.2015v28n4p169Bats throughout the world are preyed upon primarily by vertebrates, but some are also attacked by invertebrates. We report two cases of bats entangled in webs of the giant-spiderNephilingis cruentatain southeastern Brazil. The first incidence occurred in December 2012, on which a femaleEptesicus diminutuswas found dead. The second occurred in March 2013, in which a maleTadarida brasiliensiswas removed from the web alive, and later released. The animals showed no predation marks on the body, and both events were recorded after heavy rains. We suspect that the bats may have become entangled in the webs while seeking shelter from rain, or while foraging for insects. Even though the bats were not preyed upon, this spider cannot be ruled out as an opportunistic predator of small bats, as has been observed outside of Brazil.
