Oriental latrine fly Chrysomya megacephala, copyright Muhammad Mahdi Karim.

Belongs within: Calliphoridae.

The Chrysomyinae are a group of blow flies characterised by the presence of a row of hairs along the posterior margin dorsally of the stem vein (the basal section of vein R), together with a haired posterior margin on the hind coxa. Though mostly scavengers, some are known to attack living animal tissue via wounds and the screwworm fly Cochliomyia hominivorax develops as an obligate parasite of large mammals. Species of Cochliomyia may be distinguished from other members of the subfamily by the reduction of the palpus which is short, slender and filiform. The genus Chrysomya is characterised by a covering of dark appressed hair over the entirety of the dorsal surface of the lower calypter (Vargas & Wood 2010).
