1. The formation process of golden cicada
The formation of golden cicada is an important link in the life cycle of cicada insects. A cicada goes through three stages in its life: egg, nymph, and adult, and the golden cicada is born when the nymph metamorphoses into an adult.

| stage | Description |
|---|---|
| 1. Nymph stage | Cicada nymphs live underground, often for several years or more, feeding on the sap of plant roots. |
| 2. Preparation for molting | When the nymphs are about to molt, they crawl to the ground or tree trunks to find a suitable molting site. |
| 3. Molting process | The nymph's shell splits from the back and the adult emerges, leaving the golden cicada shell intact. |
| 4. Adult stage | The adults spread their wings, harden their bodies, begin to chirp, and mate, completing their life cycle. |
