The blow fly Cochliomyia minima Shannon is endemic to the Caribbean, and it has great potential for forensic applications because of its abundance and broad distribution in the region. However, its larval stages are unknown. Here, I update previously published identification keys by describing for the first time the morphology of C. minima larvae. The larvae of C. minima are found to be very similar to those of Cochliomyia macellaria F., but the former can be easily identified by the oral sclerite completely pigmented, visible as a spike between mouth hooks. The description of C. minima larvae in this study will be useful to forensic scientists in the Caribbean region.
