What does a mouse flea look like?

A mouse flea, scientifically known as Nosopsyllus fasciatus, is a small, wingless insect that typically measures about 1 to 3 mm in length. It has a flattened body, which allows it to easily navigate through fur, and is usually brown or dark brown in color. Its legs are long and powerful, adapted for jumping, and it features comb-like structures on its body that help it cling to its host. Mouse fleas are primarily found on rodents, particularly mice and rats, and can transmit diseases.
