This louse is preferentially found on the face and jaw of domestic cattle and captive ungulates, namely gazelles. They are spread through direct contact.
Sucking louse, fine mouthparts puncture the skin to feed on cattle blood.
This is the smallest of the lice found infesting cattle (1.2-1.7 mm long) and can often be confused with the long nosed sucking louse. However, it has a shorter “nose” than the long nosed sucking louse and on close examination the adults have small protuberances along the abdomen called tubercules through which they breathe (Figure 1).
The female louse lays one to two 0.70 mm long eggs per day, each attached to a hair. Often the hair is bent, a feature not observed with other cattle lice.
Heaviest infestations are usually found on the head, neck, shoulder, back and dewlap. These lice cluster on the face, especially around the eyes and muzzle. Heavy infestations give white-faced cattle a bluish appearance.
The incubation period of the eggs of this species is 11-13 days and the complete life cycle from egg to adult takes 27-29 days.
It is uncommon to find heavy infestations of this species in Australian herds.
