Colophon

The animal on the cover of Cloud Native Transformation is the Blue Clipper butterfly (Parthenos sylvia). It lives in the rainforests of India, Sri Lanka, Bangladesh, Myanmar, Papua New Guinea, and most of Southeast Asia. Its large (four inch) wingspan and beautiful colors wings make it a favorite of photographers and butterfly conservatories.

The name of the species means “virgin of the forest” in Greek. The English name refers to the 18th century clipper ships whose billowing sails the butterfly’s white wing patches resemble. The wings’ background color may be orange, green, or brown instead of blue.

The Blue Clipper is a fast, powerful flier, flapping its wings stiffly and keeping them mostly horizontal as well as gliding. The male is smaller than the female and flies closer to the ground, taking water from puddles. Both sexes also feed on nectar, often from lantana flowers. Larvae feed on tropical plants such as the passionflower and moonseed.

Many of the animals on O’Reilly covers are endangered; all of them are important to the world.
