Scanflies are large vehicles used by the Grox, though their appearance suggests they are animals. They are produced in moderately high numbers by Grox Infection Pods. It is unknown what they do when invading a planet, all they seem to do is hover above the Infection Pod. It is possible they are defending the Pod from an attack from the sky, or they might be doing precisely what their name suggests, scanning.
- In the Sporepedia, they are called "Conqrix Air Walkers."
- If you go behind the infestation pod, they will shoot a weak laser at you.
