==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.

−

*'''Resident''' biting fly

+

==Life Cycle==

−

**Spends most of ~~its time '''~~on~~'''~~ the ~~host~~ along the back, shoulders and sides

+

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.

−

*Mainly resides on cattle

+

The complete life cycle takes around a 1 week.

−

*Feed on areas where the skin is thin e.g. ~~dewlap, belly and udder~~

~~==Pathogenesis==~~

−

*Production losses

−

**Annoyance

−

**Bites can lead to secondary infection by [[Myiasis Producing 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
