Also known as: Midges
The most important veterinary species is Culicoides

Introduction

This parasite is found worldwide and attacks humans and a wide variety of animals. The only genus of the family Ceratopogonidae of current veterinary significance is Culicoides.

The midge is a vector for several viruses, including Bluetongue and African horse sickness.

It causes allergic dermatitis of horses, primarily affecting the base of the tail and the withers, and induces an intermediate-type hypersensitivity reaction to the midge saliva, known as 'Sweet itch'

Identification

Culicoides are small flies 2-5mm long with a dark colouring, more commonly known as biting midges. They have a characteristic arched thorax giving a 'hump-backed' appearance. The wings are mottled.

Life cycle

Eggs are laid onto plants near water and the larvae fall into water and pupate. The life cycle takes 6-12 months to complete in temperate climates, but can take only 1 month in tropical climates. Females of most species are adapted to sucking blood from the host.
