LUCILIA NOBILIS PARASITIC ON MAN. 



By Fr. Meinert. 



[Translated by Martin L. Lixell from the Ssertryk af Entomologiske Meddelelser, 



1 Bind, 3 Hefte, 1888.] 



It is an old story that the hnman body is snbject to attack from sev- 

 eral ecto- and endo-parasitic insects, and a whole literatnre is cited by 

 Hagen on Insecta in eorpore huniano. It is principally Dipterons larvae 

 that are recorded and described as occurring in the stomach, or vomited 

 through the month, or in the intestine or ejected through the anus, or 

 carried out with the urine, or occurring in the nasal cavities, or finally 

 living beneath the skin, in the eyes or in the ear. All recorded cases 

 are not reliable, and the jjresent author will not deny that he belongs 

 to the skei^tics in regard to many x^ublished stories, and he also thor- 

 oughly doubts that any Dipteron is sufficiently specialized to live ex- 

 clusively in or upon man, not even excepting the South American Lu- 

 cilia liominivorax. 



In recent years Dr. G-. Joseph, in Breslau, has applied himself to the 

 subject of diseases caused by or accompanied with attacks by Dii)terous 

 larvie, and he has established or more definitely determined a peculiar 

 form of disease — Myiasis or Fly- disease — in several chief forms, partly 

 as Myiasis dermatosa muscosa (caused by Muscidse) and M. der. ocstrosa 

 (caused by (Estridce), partly as Myiasis Interna and M. septica. Among 

 the Dipterous larvae mentioned by Joseph the larvae of Sarcophlla wohl- 

 farti may be of special interest. The fly was raised from larvae that 

 occurred in the nasal cavities and in the ear of man, first by Wohlfart 

 (1770) and more recently and in larger numbers by Portschinsky 

 (1875-'84),who has satisfactorily studied the species. At large the fly 

 is very rarely found. Joseph gives in his essay " JJeher 3Iyiasis externa 

 dermatosa, 1887,'' a description of the fly and its larva. 



At the end of August, 1887, I received fr^om Dr. A. Iverson a dozen 

 rather small Dipterous larvae that were said to have been taken fr'om 

 the ear of a man with ear discharges, and which he thought he got by 

 sleeping on the grass. The larvae came in glycerine and were partly 

 shriveled up, and I therefore did not think fit to do anything with 

 them, but wrote back that it was probably 8arc. wohlfarti, although
