All larval instars of Calliphora nigribasis Macquart, Cochliomyia macellaria (Fabricius), Chrysomya albiceps (Wiedemann), Chrysomya megacephala (Fabricius), Hemilucilia segmentaria (Fabricius), Hemilucilia semidiaphana (Rondani), Lucilia eximia (Weidemann) are described, but the second and third instars of Compsomyiops verena (Walter), and only the third instar of Calliphora vicina Robineau-Desvoidy, Cochliomyia hominivorax (Coquerel), Lucilia peruviana Robineau-Desvoidy, Lucilia sericata (Meigen) and Sarconesiopsis magellanica (Le Guillou). KEY WORDS: Blowfl y, key larvae, forensic entomology RESUMEN -Se presenta una clave dicotómica con ilustraciones para separar 13 especies de larvas de Calliphoridae de importancia forense en Colombia y la descripción de los estadíos inmaduros.

Several species quickly colonize human cadavers and are potentially useful in forensic studies. One of the major problems with carrion fly identification is the lack of taxonomists or available keys that can identify even the most common species sometimes resulting in erroneous identification. Here we present a key to the adults of 12 families of Diptera whose species are found on carrion, including human corpses. Also, a summary for the most common families of forensic importance in South America, along with a key to the most common species of Calliphoridae, Muscidae, and Fanniidae and to the genera of Sarcophagidae are provided. Drawings of the most important characters for identification are also included.

Five decomposition stages of pig carcasses were categorized: fresh (0-1 day after death), bloated (2 days after death), active (3 days after death), advanced (4-6 days after death) and dry (7-30 days after death). The arthropod species collected from the corpses in the field sites were mainly classified belonging to two orders and nine families, namely order Diptera (family Calliphoridae: Chrysomya rufifacies and Chrysomya megacephala, family Muscidae: Musca domestica, family Faniidae: Fannia canicularis, family Sarcophagidae: Parasarcophaga ruficornis and family Piophilidae: Piophila casei,) and order Coleoptera (family Dermestidae: Dermestes maculatus, family Histeridae: Hister sp., family Cleridae: Necrobia rufipes and family Trogidae: Trox sp).
