Bed bug (engorged nymph)

Typically found in cracks and crevices of human dwellings, particularly near sleeping areas like mattresses, bed frames, and headboards.

Obligate hematophages, meaning they feed exclusively on the blood of warm-blooded animals, primarily humans.

Nocturnal parasites that hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (egg, nymphal stages, and adult) and require a blood meal to molt to the next stage.

Risks include itchy skin welts, allergic reactions, and psychological distress/insomnia. They are not known to transmit diseases to humans. There are no ecological benefits to humans.
