Kissing bugs are members of the order Hemiptera and the genus
Triatoma. They have been associated with transmission of the parasite,
Trypanosoma cruzi, causing Chagas Disease. (Chagas Disease symptoms include fever, eyelid swelling, headache, and splenomegaly, and lead to serious heart, gastrointestinal, or neurologic complications.)
- Kissing bugs are black or brown, some having orange and black markings on the abdomen.
- Typically 1-3 cm in length.
- Antennae are four-segmented.
- The head is constricted and looks like a neck.
- The mouthparts region is called a beak and is three-segmented.
- Simple eyes and compound eyes are present.
- Triatomine bugs are also known as cone-nosed bugs (and bloodsuckers) and are typically found in the southern United States, Mexico, Central America, and South America. Eleven different species have been found in the southern US.
- Mostly active at night, feeding on the blood of mammals (including humans), birds, and reptiles.
