Chrysomya megacephala (Fabricius, 1794) is a pest calliphorid fly of medical and forensic importance. In this study, we report the first record of Chrysomya megacephala in Algeria, North Africa. In addition, other calliphorid species which are commonly present in Algeria are listed along with their occurrence locations.

Two specimens (one male and one female) of Ch. megacephala were captured in Mechtita, Tipaza Province during autumn and three samples, all females, were collected in Ouled Yaich, Blida Pro vince during spring. Three calliphorid species, namely Calliphora vicina Robineau-Desvoidy, Chry so mya albiceps Wied mann and Lucilia sericata Meigen, were recorded from our surveys of necrophagous Diptera in Algeria between 2010 and 2016. Ch. megacephala distribution seems to be moving rapidly northward in the Palearctic and the Nearctic regions. This new record expands the current distribution of this species in Africa and in the Paleartic Region.
