Food. — The blood and serous discharges oi cattle and horses. 



Status. Not definitely known to be a pest but quite likely to 

 prove one on account of its feeding habits, whereby it may carry 

 pathogenic organisms from one animal to another. 



Control. Treatment of cowdung with oily sprays or keeping in 

 suitable receptacles. 



Remarks. This species is cited here as an example of the group 

 of non-biting but bloodsucking (haematophagous) species of the 

 genus Musca, which also includes .1/. gibsoni (? recte gibsona), 

 Patton and Cragg, .1/. convexifrotis, Th.. and .1/. bezzii, P. and C. 

 These tlics are not themselves provided with biting mouth-parts 

 and are therefore unable to pierce the skin of animals to obtain 

 blood, but they rely on other biting (lies to draw blood and there- 

 upon endeavour to thrust their proboscides into the wound to obtain 

 the exuding blood, often positively worrying and driving away 

 the true biter. It is probable that this and other Hies of tin 

 may prove to be important agents in tin- conveyance of disi 

 domestil animals.
