“ The fully grown third instar larvae of Chrysomyamegacephala were collected from decaying fishes near Royapuram fishing harbour. This site is found to be the regular breeding site for Chrysomyamegacephala. Larvae were reared under laboratory condition and freshly emerged adult flies from pupae were collected and identified by morphological features and molecular tools. Molecular identification through generation of DNA barcoding using mitochondrial COI gene of Chrysomyamegacephala is appended. ”

“ Synanthropic derived form of Chrysomyamegacephala is common around human dwellings enabling direct contact with humans. It occurs on dead fish, sweets, carcasses, human excrement and fruits. The adult flies are vectors of a few infectious diseases of the digestive tract and reported to carry Morganella sp. ”

“ Dorsal cuticular spines between the prothorax and mesothorax arranged single, each having one to three dark pointed tips (Fig. 2d) . Inner dorsal tubercle moderate between middle dorsal tubercle and outer dorsal tubercle, with latter tubercle largest; a pair of the posterior spiracles clearly visible at the caudal end (Fig. 2e) . Peritreme incomplete and heavily pigmented as a dark structure encircling three relatively straight spiracular openings (slits) , with middle slits appearing slightly bent inward (Fig. 2f) . ”
