Bed Bug (Egg Casing or Cast Skin)

Indoor environments, specifically cracks and crevices in mattresses, box springs, bed frames, and furniture

Hematophagous (feeds exclusively on the blood of warm-blooded animals, primarily humans)

Nocturnal and elusive; nymphs shed translucent skins (molts) as they grow; females lay pearly white, oval eggs in hidden clusters

Risks: Bites causing itching and allergic reactions, psychological distress, and insomnia. No known ecosystem benefits in domestic settings.
