Transformer caterpillar flips over to become a scary snake

Well if it isn't the ol' snake-mimic caterpillar! Otherwise known as Hemeroplanes triptolemus, this shape-shifting larva of a sphinx moth has one of the dandiest of tricks to perform when feeling threatened. It flips up its back section to reveal a perfectly rendered snake face, complete with white spots acting as the reflection of light. Incredible! It also mimics snake behavior with actual darting gestures. If I were a bird, I'd stay so far away.

Thank you to photographer Andreas Kay who took this remarkable photo in the Amazon rainforest near Puyo, Ecuador.
