Winged Ants

A giant creature with the ability to fly.
Based on their appearance, they are believed to be a relative of the Storm Ant; however, not much else is known about them. They can spit acid while in the air, which is a deadly attack against ground units.
Because many giant creature nests appear in areas full of Winged Ants, it is thought that fully developed Winged Ants become Queen Ants.
