Triatominae, also known as "kissing bugs," are blood-sucking insects that are notorious for transmitting the parasite that causes Chagas disease. Synonyms for this taxonomic subfamily of the Reduviidae family include cone-nosed bugs, wheel bugs, assassin bugs, and blood-sucking conenoses. The name Triatominae is derived from the triatomic molecules, which are made up of three atoms, referring to the visible three-part rostrum on the bugs. Cone-nosed bugs come from the shape of their head and body. Wheel bugs are named for their wheel-like appearance and assassin bugs for their predatory behavior. Blood-sucking conenoses almost perfectly describe their feeding habits. Despite the different names, they can all be dangerous to human health, and proper prevention is key.
