Name Origin: Gromphadorhina portentosa is a species of large cockroach native to Madagascar. It is commonly known as the hissing cockroach due to the loud hissing sound it makes when disturbed. The genus name Gromphadorhina is derived from the Greek words grompha, meaning "to devour", and dorhina, meaning "gut". The species name portentosa is derived from the Latin word portentosus, meaning "ominous". This name was likely chosen due to the hissing sound the cockroach makes, which could be interpreted as a warning or omen.
