Giant Katydid

The Giant Katydid (Stilpnochlora couloniana) is a leaf-like insect. It looks like a grasshopper.

The Giant Katydid is lime green to dark-green. It has brown eyes. Its wings look like a leaf on a tree. The male has a narrower body and longer antennae than the female. It has strong hind (back) legs for jumping. The male can produce a song (to the female) by rubbing its legs to its wings. 

It grows to about 8 centimetres (3 inches) long. 

Giant Katydid

The Giant Katydid is native to Cuba. It prefers humid conditions among trees and bushes. 

It is nocturnal, which means that it is more active at night. During the day, it does not move very much. 

It feeds on plants. 

The female lays eggs on a tree branch. She glues her eggs to the branch so that they do not fall off. She lays up to 100-150 eggs in a string (line). The eggs hatch into nymphs after 40-60 days. 

The nymphs are pale green with some dark-brown markings on their back and legs. The nymphs moult several times as they grow, and gradually become adult katydids.
