The boxelder bug (Boisea trivittata) is often mistaken for a kissing bug due to its red and black coloration. They are beneficial predators in the garden. Wheel bugs are often mistaken for kissing bugs. It has a characteristic wheel on its back and red-orange markings along the side of its abdomen. The wheel bug (Arilus cristatus) is also a member of the assassin bugs group (family Reduviidae). These are some of the common insects that are often mistaken for kissing bugs. Chagas disease also can be transmitted from a blood transfusion, organ transplantation, and mother-to-baby (congenital transmission).įor more information about Chagas Disease, please refer to the Centers for Disease Control and Prevention website. cruzi parasite in North America, the likelihood of contracting Chagas disease from the eastern bloodsucking conenose bug or another native species of kissing bug is low since they do not defecate on their hosts immediately after feeding like many of the species native to Central America do.
Individuals can become infected by accidentally scratching or rubbing the insect's feces into the bite wound, eyes, or mouth. They tend to bite people on the face and right after feeding will defecate (poop). Kissing bugs hide during the daytime and come out during the nighttime when the inhabitants are sleeping. cruzi parasite is not spread through the insect's bite but rather through its feces. However, unlike other arthropod-vectored diseases such as Lyme disease, the T. cruzi parasite by feeding on an infected animal or person. Chagas disease is found worldwide, but the majority of new cases due to transmission by kissing bugs are found in rural areas of Mexico and Latin America. The main concern with kissing bugs is not their bite but instead their potential to be vectors of the parasite, Trypanosoma cruzi, which causes Chagas disease, also known as American trypanosomiasis. She will mate with several different individuals and can lay hundreds of eggs in her lifetime. Once they reach adulthood, female kissing bugs will mate, feed, and lay eggs. Time needed between life stages will vary based on temperature and host availability. Blood meal hosts may include humans, dogs, wildlife, chickens, and more. Right after feeding, some species of kissing bugs will defecate (poop), which is how the parasite Trypanosoma cruzi is transmitted. At each stage, they will take at least one blood meal before molting to the next instar. Kissing bugs go through incomplete metamorphosis, meaning they have an egg, nymph, and adult stage. They will have elongated cone-shaped heads like the adults but will not have the red-orange banding on their abdomen. Nymphs (the immature insects) range in size based on species and age. Their abdomen is wide, and the sides stick out past the wing margins, displaying six reddish-orange lines along both sides. They are dark brown to black in color, with flattened bodies. The adult eastern bloodsucking conenose bug is 3/4 inch (19 mm) long. Their legs are uniformly thin, with no 'bulging' or thicker areas on them.
Most will have some type of red-orange banding on their abdomen. They have an elongated cone-shaped head with elbowed antennae and a slender beak-like structure on the underside, which is their mouth. AppearanceĪdult Kissing bugs in general range in size from 3/4 - 1 3/4 inches in length. Triatomine species are potential vectors of the Chagas disease parasite, Trypanosoma cruzi. However, only two species of kissing bugs, Triatoma infestans, and Rhodnius prolixus, are commonly found living with humans and are considered important vectors of this parasite, and neither of these two species are commonly found in the United States.
There are 11 species of kissing bugs found in the United States, but only one species, the eastern bloodsucking conenose bug ( Triatoma sanguisuga), is found in the Mid-Atlantic region. Kissing bugs are typically found in the southern United States, Mexico, Central America, and South America. Unlike other assassin bugs which are considered to be beneficial insects in the garden and feed on other insects and invertebrates, kissing bugs are considered to be pests and most species only feed on the blood of vertebrates. Kissing bugs, conenose bugs, or vampire bugs are all common names for a group of insects in the subfamily called Triatominae, which is part of a larger group known as assassin bugs (family Reduviidae).
