Flea (likely a cat flea)

Adult fleas live on mammals, especially cats and dogs; eggs and immature stages develop in carpets, bedding, and other sheltered areas.

Adults suck blood from animals and sometimes people; larvae feed on organic debris, including adult flea feces.

Wingless, laterally flattened insects that jump readily. Eggs fall from the host, and larvae and pupae develop off-host.

Bites cause itchy irritation and may trigger allergic dermatitis; fleas can transmit pathogens and tapeworms. No notable ecological benefit around homes.
