First, collecting provenances in the field, such as eggs, larvae, pupae, adults, etc., can be collected; The second is to buy rare and high-quality butterfly varieties from butterfly breeding units and individuals. Whether it is self-collected or purchased, it is necessary to compare the butterfly color chart and the butterfly key table to identify its species and its authenticity.

2. Feeding equipment

The general butterfly breeding method is similar to sericulture. The breeding cage is made of wood strips with a length of 2m, a width of 1.5m and a height of 1.8-2m, and covered with 16- 18 mesh copper wire, iron wire or nylon cloth.

3, spawning and hatching

Wild butterflies must pair or mate and lay eggs. Generally, females like to lay eggs in leaves, fruit surfaces, smooth branches or rough gaps. Indoor breeding should prepare suitable spawning sites according to the different habits of various butterflies, such as folded paper strips, straw, branches, gauze and so on. Pay attention to moisturizing during the egg period and cover it with wet gauze. Too dry will reduce the hatching rate.

4. Larval rearing

Butterfly larvae mostly feed on leaves, stems, flowers and fruits of plants, which can be collected and raised. Unused ones can be put in bottles or wrapped with wet cotton balls to prevent wilting. The breeding density should be 65,438+0-2 butterflies per 65,438+00 square centimeters, and some butterfly species that kill each other should be raised sparsely or singly. Larvae pupate after 5-6 instars.

5, pupating

Before pupation, some paper balls, straw, wood plates engraved with dimples, etc. can be filled in the feeding cage. Put the pupa-covered object on the wet soil to keep it moist, and after a period of time, the butterfly can emerge.

6. Adult feeding

Butterflies need adequate food. Water, honey juice, syrup and milk are all commonly used liquid feeds. The concentration of sugar water or honey water is generally 1- 10%, which can be put into containers such as cups and plates or filled with absorbent cotton and gauze before feeding. In addition, different feeds can be prepared according to the "taste" of butterflies. For example, Papilio Papilio can be prepared with sucrose, glucose, dry yeast, casein, filter paper powder, Chinese cabbage leaves, etc.
