Bug Evolution Evolution Requirements: What You Need Before You Can Evolve

Quick answer

Checking whether you can evolve is built into the game: the evolve screen itself is the requirement check. When you reach an evolution point on the Bug Tree, that screen shows which bug you can pick next and its stats — if it lets you pick, you are eligible. In observed play, one spider transition, the starting spider evolving into the Housefly, asked for level 12 and 200 coins, so levels and coins are what you prepare.

• Finish the tutorial first — its opening stages gate you at level 8 before the rest of the game opens up
• Hunt ants and crickets for XP and coins; killing insects is the main way to level quickly
• At the evolution point, compare the stats shown for each option before you commit

How to check the requirement for the evolution in front of you

Bug Evolution keeps the requirement question simple: you pick your next bug on the evolve screen once the screen lets you, and that screen is the game's eligibility check for evolving. When you arrive at an evolution point on the Bug Tree, the screen tells you what you can become and when you are allowed to commit — if it lets you pick, you are eligible; if it does not, you keep growing.

The screen is also where the real decision happens, not just the eligibility check. The first evolution from the starting tiny spider offers a choice between a Grasshopper and a Housefly, and the evolve screen shows the stats of each option so you can compare them before you commit. Reading those stats is part of checking what is in front of you: the screen is the game's own summary of what each form gains, so you never have to guess what a form does before choosing it.

What a requirement looks like: the spider-to-Housefly example

One hands-on walkthrough of the first evolution shows what a requirement looks like in practice: evolving from the starting spider into the Housefly required level 12 and 200 coins. That pair of numbers comes from a single observed playthrough rather than the game's own documentation, so treat it as a confirmed example of how a requirement is presented — a level to reach plus a coin cost to pay — rather than a guaranteed price list for every transition on the tree.

The example still tells you exactly what to have ready when an evolution point gets close: experience built into your level, and coins saved up to cover the cost. It also shows why the choice matters and not just the price, because the Housefly can fly, which helps you escape danger — a useful first pickup if you keep getting eaten while you are still small.

Getting ready: meeting the requirement

The path to meeting a requirement like that is the same leveling loop every form goes through:

1. Finish the tutorial. The opening stages ask you to reach level 8 before the rest of the game opens up.
2. Eat big food orbs. Larger orbs give more when eaten, so skip the small ones when a big one is close.
3. Hunt ants and crickets. Killing insects around the map gives XP and coins, and it is the main way to level quickly — exactly what pushes you past a level gate like level 12.
4. Pick an upgrade every level. You choose one option each time you level up, so the levels that carry you toward an evolution also make your current bug stronger.

Levels and coins stack up naturally from that loop, and the grind is forgiving: dying does not reset your progress. You respawn and carry on, so the growth you have banked toward an evolution is not lost to a bad encounter.

What changes once you commit to an evolution

Two things are worth knowing before you commit:

• You start small again. After an evolution completes, you begin as a small version of the new bug and keep levelling. Being ready to evolve is a per-form state: each new form starts its own climb toward the next transition on the tree, rather than inheriting a ready-to-evolve status from the last one.
• Evolving itself is safe. While your evolution is in progress and has not finished, no one can attack you. You can commit at the screen without being punished mid-transition.

The tree beyond the first evolution

The official game description frames the whole path: you hatch as a tiny spider, eat food to grow bigger and stronger, and evolve into new insects and spiders on the Bug Tree — flies, moths, grasshoppers, tarantulas and giant prehistoric beasts are among the targets, and new insects arrive every update.

Later positions on the tree are identifiable by name even though their requirements are not published: community tier lists place the Black Widow and big spider evolutions as strong A-tier picks, moths and grasshoppers as mid-tree B-tier stepping stones, and the prehistoric beasts and top tarantula lines at the deepest S tier — with the tier lists themselves noting that these placements are community inference, not official data. No source states the numeric requirements for those later transitions, so there are no published numbers to plan around. The practical method stays the same one described above: keep levelling and saving coins, walk up to your next evolution point, and let the evolve screen tell you exactly what the form in front of you demands.
