[citation needed] Females are elongated and about 80–100 mm (3–4 in) in length, ranging from a light green to a darkish brown in colour.

Eggs are 2 mm (0.08 in) in length,[3] ovoid and brown, with a beige capitula at one end.

During the day, they rest, often with legs in line with the body, on their food plants.

Due to their inconspicuous nature, accidental introductions of C. morosus have been recorded around the world, including Great Britain, South Africa and the United States, where in some cases they have become a pest.

[4] Studies at the San Diego Zoo found the introduced species on a large number of ornamental plants.
