of war 



reported. Naturally, the fly deposits its larvae on decaying flesh. In times of 

 all of these flies become important by reason of "maggots" in the wound. These 

 larvse are the most common ones in intestinal myiases. The mouth booklets are 

 strongly curved and separate. Each abdominal segment has a girdle of spines. 

 The anterior end is somewhat pointed. The hind stigmal plate is in a deep cavity. 



CEstridse 



The flies of this family are usually called botflies. The mouth parts are almost 

 vestigial. They have a large head with a somewhat bloated-looking lower portion. 

 They are often rather hairy. The larvae which develop from the eggs are parasitic 

 either in the alimentary canal or the subcutaneous tissues. 



FIG. 88. Insects in which the larval stage is important, (i) Chrysomyia macel- 

 laria; (2) C. larva; (3) Dermatobia cyaniventris larva, early stage (ver macaque); 

 (4) D. cyaniventris larva, later stage (torcel or berne); (5) D. cyaniventris; (6) 

 Auchmeromyia luteola; (7) A.luteola, larva; (8) Sarcophaga magnifica; (9) S. magnifica 

 larva; (10) Anthomyia pluvialis; (n) A. phtvialis larva. 



Dermatobia cyaniventris. These are large, thick-set flies about % inch long, 

 with prominent head and eyes, small antennae, and a marked narrowing at the 

 junction of thorax and abdomen. The thorax is grayish and the abdomen a metallic 

 blue. The larvae are deposited under the skin in various parts of the body. When 

 the larvae move they cause considerable pain. At first the larva is club-shaped, 

 but later on it becomes oval. The former is called Ver Macaque, the latter Torcel. 



Hypoderma diana. The larval form of this fly has been reported three times
