They are large insects with metal-like skin and human-like cringing face. The beetle roaches are green and brown and their mother is pink, with a frill on her neck and is the biggest of all the roaches. All the beetle roaches follow their mother and seem to have a hive mind.
In "Storming Cloud Tower", the Winx and Specialists end up in Cloud Tower's junk yard where they come face to face with the beetle roaches until a disguised warrior comes and chases them away.
- The beetle roaches have eight legs like spiders, not six legs like insects.
- The frill of the mother beetle roach looks like the collar of Griffin's dress.
