Calliphorids are the first arthropods to colonize cadavers, their composition and abundance vary according to location. They are used to estimate post-mortem intervals and surmise the relocation of corpses; making the identification of these local variations are key in detecting the relocation of a body. We assessed these blowfly variations in 11 sites in Bogotá. A pre-sampling (dry season) was conducted to select a trapping method and sampling sites; the formal sampling (rainy season) was conducted using a directed sweep net. We identified the following species: Lucilia sericata, Roraimomusca roraima, Compsomyiops verena, Calliphora nigribasis, Calliphora vicina and Sarconesiopsis magellanica </em>and compared their richness, diversity, dominance and composition for each site. The highest richness was found in Chico-Lago (Chico) while the lowest was Alcazares (Barrios Unidos). Bolivia (Engativá) was the most diverse and 20 de Julio (San Cristobal) the least; dominance was higher in 20 de Julio and lower in Apogeo (Bosa). Species’ composition and abundance varied between sites; this may be used as evidence to support cases in Bogotá in which cadavers have been relocated.
