''S. calcitrans''are of the family ''Muscidae''.  They can feed on a number of hosts in close succession, and therefore can act as an important mechanical vector in the transmission of disease e.g. [[Equine Infectious Anemia|Equine infectious anaemia]].

==Identification==
+
*Longitudinal grey stripes on thorax
''Stomoxys calcitrans'' has a high resemblance to [[Musca spp.|''Musca domestica'']]. 
 
''S. calcitrans'' is 5-7mm long, and both the males and females suck blood. They are grey with four long longitudinal stripes on the thorax, and with large black spots on the abdomen. 
 
  
The larvae are identified by examination of the posterior spiracles.

==Life cycle==
 
==Life cycle==
Eggs are laid on manure, or rotting hay and straw. The eggs then develop into larvae in usually less than 4 days, and then transform from larvae into adults. The females require several large blood meals before they are successfully able to reproduce.

The life cycle from the production of an egg to a fully mature adult can range from 12-60 days.

Adult flies can survive for around 1 month.
