*Also known as the horn fly
+
Also known as: '''''Horn fly — Lyperosia irritans
   −
*'''Resident''' biting fly
+
==Hosts==
**Spends most of its time '''on''' the host along the back, shoulders and sides
+
Cattle
   −
*Mainly resides on cattle
+
==Identification==
 +
''H. irritans'' is of the class [[Insecta|insecta]].  Adults are between 3-4mm in length, and are grey with black stripes on the thorax. The larvae are yellow.
   −
*Feed on areas where the skin is thin e.g. dewlap, belly and udder
+
==Life Cycle==
 +
The flies remain on the host, for most of their life cycle, leaving only to lay their eggs on other hosts - spreading the infection. The eggs hatch quickly, and mature on the cattle, mostly along the back, shoulders and sides.
   −
*Common in southern England, the USA, Europe and Australia
+
The complete life cycle takes around a 1 week.

==Pathogenesis==
  −
*Production losses
  −
**Annoyance
  −
**Bites can lead to secondary infection by [[Myiasis Flies|myiasis producing flies]] and other muscid species
  −
 
  −
*Disease transmission
  −
**Pathogenic bacteria and viruses via mechanical transmission
  −
**Helminths can be introduced into the host
  −
***E.g. ''Stephanofiliaria'' a filarial nemadode found in the skin of cattle overseas
  −
 
  −
==Control==
  −
*Resident fly so easier to control than visiting flies as spends more time in contact with the host
  −
 
  −
*However, [[Ectoparasiticides|insecticide]] resistance can occur quicker
