Musquito. 17 



riage, production of its progeny, and funeral, are often celebrated in 

 one day. The phryganea is another fly of this order; the larva lies 

 concealed under the water in moveable cylindrical tubes of their own 

 making. In the fly-state they institute evening dances in the air in 

 swarms, and are fished for by the swallows. 



Many other flies, who do not leave their eggs in water, contrive 

 to lay them in moist places, as the oestros bovis; the larvre of which 

 exist in the bodies of cattle, where they are nourished during the 

 winter, and are occasionally extracted by a bird of the crow-kind 

 called buphaga. These larvje are also found in the stomachs of 

 horses, whom they sometimes destroy; another species of them adhere 

 to the anus of horses, and creep into the lowest bowel, and are called 

 botts; and another species enters the frontal sinus of sheep, occasion- 

 ing a vertigo called the turn. The musca pendula lives in stagnant 

 water; the larva is suspended by a thread-form respiratory tube; of 

 the musca chamasleon, the larva lives in fountains, and the fly occa- 

 sionally walks upon the water. The musca vomitoria is produced in 

 carcases; three of these flies consume the dead body of a horse as soon 

 as a lion. Lin. Syst. Nat.
