common blow flie

The common blow fly (<em>Calliphora vicina</em>) is a large, metallic-blue fly belonging to the family Calliphoridae. It is classified as Least Concern on the IUCN Red List and has been recorded across terrestrial and freshwater habitats in Africa, including South Africa, as well as across five European countries and the United States. <em>Calliphora vicina</em> is one of the most familiar blow fly species in temperate regions, often found around human settlements, carrion, and organic waste. It plays an important ecological role as an early colonizer of decomposing animal matter, and its predictable developmental stages make it a key species in forensic entomology for estimating post-mortem intervals. Adults typically feed on nectar, pollen, and decaying matter, while larvae develop in carrion or, occasionally, in wounds. The species is cold-tolerant and often active during cool weather when other blow flies are less abundant. Biological traits of this species remain poorly documented in the scientific literature.
