Eumorpha labruscae

Eumorpha labruscae, is an exotic hawkmoth that can grow to the size of your hand. This migrating moth is commonly found in South and Central America, and occasionally as far north as Canada. It is known as the gaudy sphinx thanks to its remarkable markings and the amazing array of colours on its wings. Discover how its colourful larvae mimic a snake to avoid predation, and how the adult moth seeks out a mate.   

Eumorpha labruscae, the gaudy sphinx, is a Neotropical hawkmoth with a relatively large geographical distribution.

It has a combination of green, blue, red and yellow colouration on the wings which gives it an exotic and impressive appearance and also explains its flamboyant common name.

The moth’s Latin name is composed of the Greek word Eumorpha which means well-formed, and labruscae the Latin word for fox grape (Vitis labruscae) - one of the plants on which the larva feeds.
