Caedicia simplex is a New Zealand native insect in the grasshopper family Tettigoniidae. Insects in the Genus: Caedicia are commonly called Katydids. Caedicia simplex is also found in Australia. It has a length 42 mm including wings. The lifespan of a katydid is about a year, with full adulthood usually developing very late in the lifecycle.It is common in New Zealand gardens where it is well camouflaged on shrubs and plants because of its colour and leaf patterns on its wings.  It feeds on foliage. It can jump or fly.  It also makes a feeble chip in the evening. It is named after the call of the American native katydid. "Katy did  Katy didn't". 

There are a rare pink/red and a yellow form which is due to a genetic mutation known as erythrism, similar to the recessive genes that cause pigment disorders that afflicts albino animals.
