Solenopsis invicta - red imported fire ant

Male ants, such as the winged individual here, are very different creatures to the females.  They are designed for flight and for reproduction.  Notice the different sizes of worker ants in the picture.  Such size polymorphism in the worker caste is typical of both native and introduced species of fire ants.
