 “Two forms of Chrysomya megacephala were recognized earlier, the normal form (nf) and the synanthropic derived form (sdf). The synanthropic derived form differs from the normal form due to sharp demarcation between upper larger and lower smaller ommatidia. The normal form is confined to forests of South Pacific Islands (from Bismarck to Archipelago to Western Samoa), while synanthropic derived form has spread around the World from PNG. The discovery of feral derived form (fdf) from India, which is a morphological intermediate between normal form and synanthropic derived form, has raised questions about the ecological and evolutionary tendencies of this fly. The discovery suggests that some other relic populations are still existent in other parts of Indian sub-continent.”
