Definition

Noun: A small, wingless insect that is parasitic on warm-blooded animals. It has a flattened body and feeds exclusively on blood by sucking. This term refers specifically to insects of the order Anoplura, commonly known as true lice.

Usage

The term "sucking louse" is a scientific and zoological term used to describe a specific type of parasitic insect. It is typically used in formal, academic, or technical contexts such as biology, veterinary science, or medicine.

Examples

• The veterinarian identified the parasite as a sucking louse, which was causing anemia in the cattle.
• Sucking lice are highly host-specific, meaning each species usually infests only one type of animal.
• Unlike biting lice, a sucking louse has mouthparts adapted for piercing skin and sucking blood.

Advanced Usage

• The term is often used in contrast to "biting louse" (order Mallophaga), which feeds on skin debris and feathers rather than blood.
• In epidemiological studies, sucking lice are noted as vectors for certain diseases, such as epidemic typhus.
