The inadvertent inclusion of weevil‐infested seeds when evaluating seed predation by vertebrates, and particularly rodents, may lead to an overestimation of predation rates, thereby confusing the roles of rodents and invertebrates as ecological filters. A study of weevils, rodents and Syagrus romanzoffiana palm seeds indicates the usefulness of X‐rays to improve evaluation of invertebrate seed predation.
