70 FLTK.S FOK MARCH. 



No. 6. COW-DUNG FLY. 



This fly is to be seen throughout the year. 

 It is very abundant about the middle of March, 

 "vvhen vast quantities are seen upon the water if 

 there be a high wind. The colour of the male, 

 when newly hatched, is a very bright tawny 

 yellow, that of the female a greenish brown ; she 

 is rather smaller than the male, is found in as 

 great numbers on the water, and is as good a fly 

 to imitate. This insect is not in full season after 

 the end of April, but in very blustering days 

 may be used all the year round. It is a fly that 

 varies much in size, the early specimens being 

 mostly small.
