above, made in Illinois under different conditions as iet,^uds

 breeding habits are practically the same whatever the geographical 

 position or climatic conditions may be. 



Milliken (1011) found the eggs and larvae of M. domestica in 

 alfalfa or lucerne ensilage in Kansas, U.S.A. The fermentation 

 taking place no doubt attracted the adult Hies. 



Pratt (1912) bred fifty specimens of M. domestica from cow- 

 manm'e at Dallas, Texas, U.S.A. He states that "this is one 

 of the most common species in stables. Fresh manure attracts 

 it in great numbers." 



Paine (1912) made a study of the species of flies breeding 

 in garbage in the city of Boston, Mass., U.S.A. Larvae were 

 collected from the contents of garbage-pails as they were emptied 

 into the scavenger's waggon. In some cases they were so abun- 

 dant that the interior of the receptacle appeared as a wriggling 

 mass. The larvae were allowed to complete their development 

 under laboratory conditions, being fed on moist bread ; they 

 pupated in a small quantity of earth. The following table gives 

 the results of these rearings :
