The Flat-horned Hissing Cockroach, also called just Flat-horned Cockroach and Flat Horn Hisser, is, like other
hissing cockroaches, native to Madagascar. Adults have a mahogany red, flattish body and two small flat horns (larger on the
males that use them for fighting) between their antennae. Head and body length can be up to some 3 inches long.
