Its common name derives from its black and orange-yellow striped coloration and its hissing sound when disturbed,{{cn|date=October 2020}} which is produced when they forcefully expel air through the specially-adapted respiratory openings (spiracles) on the fourth segment of their body. Body length varies around 35–50 mm for females, and 40–50 mm in males.{{cite journal|last=Van Herrewege|first=C.|year=1973|title=Contribution à l'étude des Blattaria de la Faune Malgache. II.
