Triatominae are a subfamily of insects commonly known as kissing bugs. They are primarily found in the Americas and are known for their blood-feeding habits, often biting humans and animals during the night. These insects are characterized by their elongated bodies, long legs, and distinctive mouthparts adapted for piercing skin. Kissing bugs are significant because they can transmit Trypanosoma cruzi, the parasite responsible for Chagas disease. This disease can lead to serious health issues, including heart and digestive problems. Preventing contact with kissing bugs is essential for reducing the risk of infection.
