There are many Leaf Insects, the Philippine Leaf Insect is the commonly available species and easy to cater for. House them at room temperature (around 20-25C), in a glass vivarium with a mesh ceiling (this will aid them shedding their skin). Plenty of twigs and branches for climbing, and food consists of bramble leaves (older leaves, young hairy ones can be toxic to them), rose and oak leaves. Of course make sure all food offered is free from pesticides. Place the bramble twigs, complete with leaves in a jar of water to keep fresh – for safety use a sponge to stop the insects drowning in the water. Winter can be a problem obtaining food, keep this in mind. Spray the vivarium lightly with tepid water every day. Having a layer of moisture retaining substrate on the bottom of the vivarium will help maintain a good level of humidity.
