How to Evolve in Bug Evolution
Last updated:
Evolving is the whole point of Bug Evolution. The good news: the game always tells you what you evolve into next and at which level. It's printed on the level bar at the bottom of your screen.
Where to see your next evolution
Look at the text under your HP bar. It shows your current bug and the next one, for example:
- "SPIDERLING · Garden Spider at Lv 12"
- "YOUNG FLY · Mosquito at Lv 40"
How to evolve, step by step
- Eat food and complete quests to earn XP.
- Reach the level shown on the bar.
- Tap the ⚡ Evolve → [bug] button above the level bar.
- Your model, size and stats change to the new form.
The Evolve button can also appear before you reach the level with a Robux price on it (for example "Evolve → Mosquito ◎ 25"), which is the paid skip. Ignore it if you want to evolve for free.
