Sarcophagid flies were collected monthly during the period from December, 2005 to November, 2006 from east and west regions of Assiut city. The results obtained showed that sarcophagid flies could be collected allover the year with variation of their population density in different seasons. The majority of the collected species were abundant during spring and summer. In the present investigation, 12 species belonging to 6 genera were collected. The species Parasarcophaga aegyptiaca was the most abundant followed by Parasarcophaga argyrostoma, while Apodacra dasystigma was the least abundant species. Myiasis of man and animals is real welfare problem of world wide distribution particularly in animal arising in countries. Addition the present work provides the ultrastructural of Parasarcophaga argyrostoma the predominant species that cause myiasis in Assiut. The present work added new features that could be helpful for species identification. These features included number and arrangement of papillae on the anterior spiracles, structure of spines shape and arrangement of circumspiracular papillae at caudal segment and branching peculiarity of the posterior spiracular hairs. These new addition could benefit future identification of the Parasarcophaga argyrostoma larvae in Egypt.
