<unk>  is an obligate blood feeder that will normally attack its host at night, but will occasionally feed during the day. Adults are long, with long legs and usually a grayish-white body, which becomes reddish-brown when engorged. After feeding, they hide in cracks and crevices away from light sources, where they mate and lay eggs. Mites progress through five life stages: egg, larva, protonymph, deutonymph and adult. Under favourable conditions this life cycle can be completed within seven days, so populations can grow rapidly, causing anaemia in badly affected flocks of poultry. Young birds are most susceptible. The mites can also affect the health of the birds indirectly, as they may serve as vectors for diseases such as Salmonellosis, avian spirochaetosis and Erysipelothrix rhusiopathiae.<unk>  can survive for up to 10 months in an empty hen house. Temperatures greater than and less than , have been found to be lethal.
