Definition
The Order Anoplura comprises sucking lice, wingless parasitic insects that exclusively feed on the blood of mammals. They are highly host-specific, meaning different species of lice typically parasitize different species of mammals. Their bodies are flattened, allowing them to move easily through the fur or hair of their hosts. Imagine them as highly specialized blood-sucking freeloaders. They possess piercing mouthparts perfect for drawing blood. They are a common source of irritation and can transmit diseases.
