The genus name comes from Greek: a(n) (negation) and ophthalmos 'eye', literally "eyeless". The species exhibits no notable characteristics, such as extravagant colors or unusual antennae , but is of interest to beetle collectors (and also collectors of Hitler memorabilia ) as a result of its name.

Thread-legged bugs – subfamily Emesinae, including the genus Emesaya Kissing bugs (or cone-headed bugs) – subfamily Triatominae , unusual in that most species are blood-suckers and several are important disease vectors
The level of cantharidin in blister beetles can be quite variable. Among blister beetles of the genus Epicauta in Colorado, E. pennsylvanica contains about 0.2 mg, E. maculata contains 0.7 mg, and E. immaculata contains 4.8 mg per beetle; males also contain higher levels than females.
The members of the Triatominae / t r aɪ. ə ˈ t ɒ m ɪ n iː /, a subfamily of the Reduviidae, are also known as conenose bugs, kissing bugs (so-called from their habit of feeding from around the mouths of people), [1] or vampire bugs. Other local names for them used in the Americas include barbeiros, vinchucas, pitos, chipos and chinches.
Also known as the Chagas disease, the life-threatening illness is passed to people by this freaky little guy, called a "kissing bug" or "assassin bug." And the Centers for Disease Control and ...
There are currently around 28,000 new cases of Chagas disease annually, a significant decrease from 700,000 new cases diagnosed in 1990. [6] Like other species of kissing bugs, Triatoma sanguisuga is known to bite humans in the face, usually around the mouth or eyes, and feed off the blood. This normally occurs during sleep.
The beetles' glands store enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. In some cases this is enough to kill a predator. [6] The main component of the beetle spray is 1,4-benzoquinone, an irritant to the eyes and the respiratory system of vertebrates.
Chagas disease is caused by infection with the protozoan parasite T. cruzi, which is typically introduced into humans through the bite of triatomine bugs, also called "kissing bugs". [4] When the insect defecates at the bite site, motile T. cruzi forms called trypomastigotes enter the bloodstream and invade various host cells. [ 5 ]
