The term 'wingless, bloodsucking insect' can be summarized as a LOUSE, which is a small parasitic insect that feeds on the blood of humans and other animals. Lice are wingless insects that live in the fur or feathers of their hosts, and they can cause skin irritation and itching. They are usually spread through direct contact with an infested person or animal, or through contact with contaminated items such as clothing, bedding, or furniture.
