Triceratopyga, is a common and synanthropic genus of medical and forensic significance in eastern Asia which have includes only one species, Triceratopyga calliphoroides. In this study we are reporting the complete mitogenome of the only member of the genus Triceratopyga. The structure of the compete mitogenome is similar with the common ancester fly mitogenome. The size of the mitogenome is 16,529 bp. This is the longest mitogenome recorded from the family Calliphoridae. Although the size of mitogenome is longer than previous records, structure and gene positions are identical with ancestral insect genome.

Calliphora is a genus from the family Calliphoridae, which includes blow flies and bottle flies. Calliphora flies are one of the most entomologically important fly species because of their relative time of arrival and colonization to animal carcasses. Until now there are only three complete mitochondrial genome recorded from the genus. In this study we added a new complete mitochondrial genome record from the species Calliphora lata. Although genome structures and gene orientations of the four Calliphora flies mitochondrial genome are identical. The size and nucleotide composition of the genomes are slightly different.
