Stick insects

Source: EZNC
Stick insects eat fresh leaves. Some species eat only one type of plant, while other species eat a great diversity of plants. Most types of stick insects eat bramble leaves.
Brown edges on the leaf are not eaten and should be cut. Edges that are too hard for small nymphs can also be cut. Alternatively, put the nymphs with other stick insects that do eat and thus cut into the edges. Do not collect feeding plants close to busy roads, industry or areas that have a poison danger, like agriculture. Scrape the thorns off and also remove the lowest leaves, as they will rot under water. Check the branches well for spiders and insects and flush away dirt. Spray every evening with drops of water, but make sure that the branches do not stick to the drops of water against the glass.
