Flea (possibly human flea)
Scientific Name: Pulex irritans (or other species in Siphonaptera)
Order & Family: Order: Siphonaptera, Family: Pulicidae (or others)
Size: 1.5 to 3.3 mm

Natural Habitat
Fleas thrive in warm, humid environments. They are often found on hosts (mammals, birds) and in their immediate surroundings like bedding, carpets, upholstered furniture, and cracks in floors.
Diet & Feeding
Adult fleas are obligate hematophagous parasites, meaning they exclusively feed on blood from a host. They bite frequently to obtain blood meals.
Behavior Patterns
Fleas are wingless insects known for their exceptional jumping ability, used to move between hosts and escape danger. They have a complete metamorphosis life cycle (egg, larva, pupa, adult). Larvae feed on organic debris, including adult flea feces ('flea dirt'), while adults are parasitic on warm-blooded animals.
Risks & Benefits
Risks: Fleas are a nuisance, causing itchy bites, skin irritation, and potentially allergic reactions in humans and pets. They can transmit diseases such as murine typhus and plague (though less common in modern developed countries), and act as intermediate hosts for tapeworms. Benefits: None for humans; they are part of the food chain in nature for some predators.
