Chrysomyinae
blow flies
Chrysomyinae is a subfamily of blow flies (Diptera: Calliphoridae) distinguished by a setose stem vein. The subfamily includes approximately 11 genera, with some groups endemic to the Neotropical region and others exhibiting broader distributions. Members are primarily necrophagous and hold significant forensic importance as indicators for estimating time of colonization and post-mortem intervals. The Neotropical lineage likely originated during the Middle Miocene, with subsequent dispersal to Nearctic and Paleotropical regions.
