In the Dragonology series, Amphitheres are an American type of dragon, having only its wings as limbs. There are three species of amphithere (Draco Americanus tex, Draco Americanus mex, Draco Americanus incognito) living in the Americas. They are rainbow colors and have fur. The egg of the said dragon is light green and has paler green markings. It will eat any large mammal from the plains including stupid humans. The prefered nesting place is in a cave or large mound of boulders. To kill its prey it scares them over cliffs. It is 15 feet long and 10 feet high. The life span of an American Amphithere is about 250 years.
The Mexican Amphithere (Draco americanus mex) is an enigmatic dragon which could have inspired the Aztec god Quetzalcoatl.
It is 5 to 10 feet high and 45 feet long. Colouration is iridescent blue-green with a paler green belly. The wings turn purple while the mane and tail feathers turn gold in the breeding season. It squawks in a manner similar to a parrot and eat large land animals, like llamas. Lairs are found near water, with their nests resembling coracles containing three hard eggs. Eggs are able to float and are brown with orange markings. Chicks have to wait in rocky holes for three years until their wings grow. Aveloca, the most famous Amphithere lived to 223.
The American Amphithere (Draco americanus tex), or Moth Dragon as it only hunts at night, is not known for a sanguine outlook. Instead, it will bite at anything.
It is 15 feet long and 8 to 10 feet high. Colouration is typically iridescent purple with a yellow belly and wings, although red, blue and green have been seen. It has a high-pitched squawk and, unusually, flocks together. Moth dragons will eat any large mammals, mainly bison and sometimes including unwary cowboys. They can breathe fire and hover, with their prefered lair high up in sandstone valleys such as Monument Valley in Utah. Eggs are bright green with phosphorescent paler green markings. The chicks can fly from birth but are quite uncertain for a few years.
In the Southeastern United States, they have been known to eat mostly children.
