The stilpnochlora Couloniana is a lime to dark green colour and has brown eyes. The nymphs are a paler green and has some dark brown markings on their back and legs. The body of a female is around 4 cm long, including the wings it's a total of 7 cm. The males are slightly smaller and less bulky, including the wings there around 6 cm. The males also have a more narrow body and a longer antenna. The hind legs of this species are designed for jumping.
The adult Stilpnochlora Couloniana are generally quite docile and do not jump as often as the nymphs do. The first reaction for the adults is to stay still then jump and fly away. The nymphs can jump at the littlest disturbance. This species is night-active meaning they stay quiet during the day, whilst they move and feed during night. Males can make a song to attract females by rubbing it's legs to their wings. This is not a continuous sound like crickets but rather a short one and not so intense.
To ensure you can house and feed them you need 30 cm in height but more is always better. For one couple of adult katydids you need 30 x 30 x 30 cm or more, preferably double that size. The enclosure should be bigger if your housing more than one adult couple or many nymphs.
Temperature should be around 25 to 30 degrees. You can do this by having more than one mesh sides or if the room is cold you can use a heat mat. The humidity should be high for the species, spray the cage every day and the top and bottom and all sides of the cage. nymphs need a lot of light but DO NOT put them in direct sunlight it's best to put a light bulb around 20 cm away from the tank as direct sunlight can be harmful.
Food and Feeding.
The katydids eat a variety of plants Oak, bramble, hazel, hypericum, butterfly bush (buddleja) apple, rose and hawthorn. You can keep the leaves fresh by cutting of the branches and putting them in a clean jam jar full of water and placing in the middle of the tank. If your housing a small nymph be sure to cover up the water with leaves or something else otherwise it could drown.
It's not hard to breed katydids, all you need is and adult couple (male and female) plenty of food and the right humidity and temperature. When the environment is right for them they will breed by themselves. The female will find a suitable branch and nibble on it to make a rough coating. She will then glue the eggs on. She can lay around 100 to 150 eggs. These will take 40 to 60 days to hatch. Remember the eggs still need the right humidity and temperature. When born there very fragile and can already jump pretty far. Low humidity can cause them to get stuck in their skin whilst molting so it's extremely important you keep spraying the tanks with a spray bottle every day.
