Resumen

Sampling with a single bait as a lure is a commonly used practice in studies of necrophilous insect
communities. Here, we determined if there were differences in necrophilous insect species richness and abundance
when attracted to 4 types of carrion: squid, bird, lizard, and mouse. A comparison between necrophagous and predatory
insects was also made to detect whether they differ in their abundance, depending on the bait used. Thirteen species of
Silphidae, Staphylinidae (Coleoptera), Calliphoridae, and Sarcophagidae (Diptera) were collected in the baited traps;
no single bait was able to attract all species. The abundances of 5 species varied significantly depending on the type
of bait used. Predatory insects were less abundant than necrophagous insects in lizard and mouse baits. These results
show that an evaluation of the structure of a necrophilous insect community can depend on the bait used for sampling.
