Lucilia coeruleiviridis, formerly Phaenecia coeruleiviridis, is commonly known as the green bottle fly, because of its metallic blue-green thorax and abdomen. L. coeruleiviridis was first discovered by French entomologist Justin Pierre Marie Macquart in 1855. It belongs to the Calliphoridae family and is one of many forensically important Diptera, as it is often found on decaying substances. L. coeruleiviridis is one of the most ubiquitous blow fly species in the southeastern United States, particularly in the spring and fall months.
