Common Flea

Typically found on domestic pets, in carpets, bedding, and floor cracks where host animals rest.

Hematophagous (blood-feeders); adults consume blood from mammals and birds, while larvae feed on organic debris and 'flea dirt' (adult excrement).

Flightless but capable of jumping long distances; they are external parasites that undergo complete metamorphosis (egg, larva, pupa, adult).

Risks include skin irritation, allergic dermatitis, and transmission of diseases/parasites like tapeworms or typhus; they offer no known ecological benefits to humans.
