Pathogenesis. — Normally the larvae breed in carrion and in the 

 bodies of insects, but one case of auricular myiasis in man has been 



reported. 



SARCOPHAGA FROGGATTI Taylor 



Geographical Distribution. — Oriental Region : Philippine Islands. Australian 

 Region: Western Australia, Northern Territory, Queensland, New South Wales, 

 Samoa. 



Pathogenesis. — Though normally a carrion feeder, it is a secondary 

 parasite of sheep in tropical and subtropical Australia. It is included 

 here because of the possibility that it might be involved in human 

 myiasis. 



SARCOPHAGA CARNARIA (Linnaeus) 



Recognition Characters. — Adult: The following characters will distinguish 

 it from most Palaearctic species : There are four distinctly developed post- 

 sutural dorsocentrals, although the hind two are a little stronger than the front 

 two ; the second, as well as the third and fourth, abdominal segment is provided 

 with median marginal bristles ; and the male genitalia are black or distinctly 

 blackish. Two subspecies have been recognized, but they are not considered here. 



Geographical Distribution. — Palaearctic Region : Widespread throughout 

 most of the region, but, according to Rohdendorf (124), absent from China and 

 Japan. Ireland, Scotland, England, Portugal, Spain, France, Netherlands, Swit- 

 zerland, Italy, Sicily, Finland, Estonia, Lithuania, Denmark, Germany, Poland, 

 Czechoslovakia, Austria, Hungary, Yugoslavia, Rumania, Bulgaria, Russia (all 

 parts of European Russia north to the Timansk tundra), Georgia, Azerbaijan, 

 Armenia, Morocco, Libia, Egypt, Syria, Palestine, Iran, Kazak, Uzbek, Turkmen, 

 Tadzhik, northern Urals, Siberia (Abakan, Lake Teletskoe, Mariinsk, Minusinsk, 

 etc.), Lake Baikal, Irkutsk, Yakutskaya Republic (Yakutsk, Zhigansk), Mongolia. 



Pathogenesis. — This species is a common cause of myiasis in some 

 parts of its range. In Britain it is a sheep maggot and in Italy and 

 Sicily it is said to be common in wound myiasis. Larvae will attack 

 wounds and body openings; cases of myiasis of the ear, eye, nasal 

 cavities, mouth, and vagina are recorded. Portchinsky states that 

 many cases attributed to this species are really due to Wohlfahrtia 

 magnified; but enough cases outside the range of that species, and 

 cases authenticated by the determination of adult specimens, are on 

 record to make Sarcophaga carnaria an etiological agent of some 

 importance. Several cases of supposed intestinal myiasis have been 

 recorded, but these are probably due either to misidentification or 

 to contamination of stools. 



SARCOPHAGA ALBICEPS Meigen 



Synonym. — Parasarcophaga albiceps (Meigen). 



Georgaphical Distribution. — Palaearctic Region : Scotland, England, Spain, 

 France, Netherlands, Italy, Finland, Germany, Austria, Hungary, Czechoslovakia, 

 Yugoslavia, Rumania, Bulgaria, Russia (south of Leningrad), north Caucasus, 

 Georgia (Abkhasia), Egypt, Sinai Peninsula, Palestine, Siberia (Omsk, Minu- 

 sinsk), Altai Mountains, Irkutsk, Ussuri, Turkestan, China, Japan. Oriental 

 Region : Indo-China, India, Ceylon, Burma, Taiwan, Philippine Islands, Java, 

 Lombok. Ethiopian Region: Tanganyika. Australian Region: New Guinea, 

 Sakeemi, Siwi, Hawaii, Guadalcanal, Samoa, New Britain. 



Pathogenesis. — Normally breeds in carrion and excrement, but has 

 been recorded in traumatic myiasis in a bull.
