Preparation materials: origami, knife and pencil.

1. Prepare an origami, a pencil and a knife. These are all necessary tools for hand origami in an emergency. Then fold both sides of the origami towards the middle. Angle along the dotted line; Open and fold.

2. Fold along the dotted line. Fold toward the center along the two corners of the dotted line. Fold along the dotted line.

3. Fold along the dotted line and turn it over. Fold along the dotted line. Fold back along the dotted line. Fold the angle into an arc, and the longicorn will be finished.

Anoplophora longicorn is an herbivorous insect, and its main food is:

1, plants

Anoplophora longicorn mainly feeds on plants, eating roots, stems, leaves, flowers and fruits of various plants. Among them, longicorn larvae mainly eat xylem of plants, such as roots, stems and branches, while adults mainly eat nectar and fruits. Anoplophora longicorn will choose different parts to feed on according to the nutrition and taste of plants. For example, for willow trees, longicorn mainly eats bark and sap, while for pine trees, it mainly eats pine needles.

2. Fungi

Both adults and larvae of longicorn beetles can eat fungi, such as mushrooms and ganoderma lucidum. In some special cases, longicorn beetles even eat rotten plants and humus.

3. Rotting animals

Horned beetles also feed on decaying animals, such as dead insects and dead fish. This is mainly because longicorn needs water and salt, and eating rotten animals can meet its needs in this respect.

Immortal beetles will also kill each other. Especially when food is scarce, longicorn will kill each other. Larvae also kill newborn larvae. In order to prevent longicorn beetles from killing each other, several longicorn beetles can be raised at the same time in the longicorn farm, and the environmental conditions of the farm, such as temperature, humidity and food, can be controlled to ensure the normal growth and reproduction of longicorn beetles. The food sources of longicorn beetles are extensive, and plants, fungi and decaying animals can all be their food sources. At the same time, longicorn beetles will also change their eating habits according to the changes in the environment and adapt to different environments.
