Every run in Bug Evolution, Corgi Crew’s Roblox survival game, starts the same way. You are an egg on a busy 15-player server, surrounded by glowing orbs and much bigger bugs that can eat you. The early hours follow a fixed pattern. You eat orbs to level up, evolve through life stages at set levels, pick passive traits at milestones, and spend coins on the Bug Tree to unlock a new bug line. The first unlocks are the Grasshopper and then the Jumping Spider.
Quick answer: Grow your starting Garden Spider to Level 12. Then open the Bug Tree and pay 200 coins for the Grasshopper. Grow that to Level 15 and pay 450 coins for the Jumping Spider.
Your first life in Bug Evolution: egg to Garden Spider
You don’t need to bring anything into your first session. The starting bug line is free, and new players get a Bonus XP (new player) boost that speeds up the opening levels. Here is the order things happen in.
A “NEW BUG READY!” popup can appear in these early minutes. It offers to unlock the Housefly for 200 coins. You can ignore it for now, because it comes back. The Bug Tree is where you choose your next bug.
Evolution levels for the first three bugs
Every bug goes through the same three stages: egg, a juvenile form, then the adult. Evolving between stages happens automatically once you hit the level. Each bug sets its own thresholds, and later bugs take longer to reach adulthood.
| Bug | Juvenile stage | Juvenile at | Adult at |
|---|---|---|---|
| Garden Spider | Spiderling | Level 5 | Level 12 |
| Grasshopper | Nymph | Level 6 | Level 15 |
| Jumping Spider | Spiderling | Level 5 | Level 28 |
A newly unlocked bug starts again as an egg at Level 1. Buying the Grasshopper doesn’t carry over your Garden Spider’s levels. You hatch a Grasshopper Egg and work through the Nymph stage to the adult form at Level 15.
The Grasshopper line has its own trait prompt at Level 10, just like the spider. Its adult form comes at Level 15, three levels later than the Garden Spider’s.
The Jumping Spider is a much longer climb. You stay a Spiderling from Level 5 until Level 28, and you pass several trait milestones along the way. Its adult form also unlocks “JUMPING SPIDER MASTERY 1.”
Traits: what to pick at milestone levels
Traits are passive bonuses. At milestone levels, the game offers three at random, and you keep the one you choose. The first prompt comes at Level 10. Longer bug lines add more, and the Jumping Spider line asks you to choose at Levels 13, 16, 19 and 20. Some traits are pure upgrades, while others trade one stat for another, so read the second half of each card.
| Trait | Bonus | Drawback |
|---|---|---|
| Skitter | Sprint costs -25% stamina | Health -4% |
| Iron Gut | Healing +15% | Bite Damage -6% |
| Glass Fangs | Bite Damage +15% | Max Health -8% |
| Long Legs | Move Speed +8% | None |
| Big Appetite | XP Gain +10% | None |
| Long Reach | Bite Reach +15% | None |
| Thick Carapace | Max Health +12% | None |
| Springy | Jump costs -40% stamina | None |
| Hardened | Damage Taken -8% | Move Speed -4% |
| Serrated Edge | Bite Damage +8% | None |
The traits fall into movement, defensive and offensive groups. If you’re new, Big Appetite speeds up every later level. Long Legs and Skitter help you get away from larger players. Glass Fangs hits harder, but it makes you easier to kill. That’s a poor trade when nearly everyone on the server outranks you.
How to unlock the Grasshopper and Jumping Spider on the Bug Tree
The Bug Tree is the menu where you spend coins on new bug lines. Each bug lists its tier, your best level with it, its stat grades and its unlock conditions. The conditions are always the same type. You must own the previous bug, grow it to a set level, and pay the coin price.
| Bug | Tier | Requirement | Cost |
|---|---|---|---|
| Grasshopper | 2 | Own Garden Spider, grow it to Lv 12 | 200 coins |
| Jumping Spider | 3 | Own Grasshopper, grow it to Lv 15 | 450 coins |
The Grasshopper’s stat card reads Speed A, Health D, Bite Dmg D, Bite Spd B and Stamina B. It’s a fast, fragile bug. The Jumping Spider reads Speed B, Health D, Bite Dmg C, Bite Spd S and Stamina C, so it trades some speed for the best bite speed of the three.
The “NEW BUG READY!” popup is another way to buy a bug. It appears whenever a new unlock is available, and it can show up mid-fight. It offered the Housefly for 200 coins early on. Once the Jumping Spider reaches its adult form, the popup offers the Mosquito for 19 Robux, or 1,800 coins if you save up.
If you prefer to buy straight from the popup, its Unlock button charges the listed price immediately. That’s why it’s worth checking your balance first, so you don’t spend coins you were saving for a different branch.
Earning coins and XP faster
Coins come from quests, survival and timed rewards. Your opening goal is the 200 coins for the Grasshopper, then the 450 for the Jumping Spider, so these sources matter from the first minute.
Quests in the Quick objectives tab
The Quick tab on the objectives panel tracks short tasks, such as staying alive for a set time, eating XP orbs, eating bugs and breaking objects. Completed quests pay coins right away with a “QUEST COMPLETE!” banner. “Eat 120 XP orbs” pays +120 coins, and “Stay alive for 3 minutes” pays +36 coins.
The bug-eating and object-breaking tasks stay on the panel as you move around, so you can work on them while farming orbs.
Playtime rewards and server events
Staying on a server triggers a PLAYTIME REWARD popup worth +100 coins. You collect it with the CLAIM! button. Server-wide events pay more. The Giant Void Mosquito boss spawns at the Void Gate by Muddy Lake, with a five-minute warning first. When the gate opens, a JOIN THE FIGHT prompt lists +1,000 Void Credits, +300 coins and 2 free spins. Void Credits go toward the Void Spinner, and only the bugs that took part get paid when the boss falls.
XP boosts: Night Hunt and bonus zones
Night Hunt is a timed phase that gives 1.5x XP, so it’s the best time to farm orbs and quests. Some areas also act as bonus XP zones, with a “BONUS XP ZONE” banner when you enter, such as the Whispering Woods. The new-player XP bonus ends eventually. A notice tells you when it’s over and points to a paid 2x XP button that lasts permanently.
Bug Evolution zones and recommended levels
When you enter a zone, a banner at the top of the screen shows its name and recommended level. The levels are guidance, not locks, so you can walk into a high-level zone early. Expect to meet bugs that can eat you there, like the Big Centipede that lives in the Web Caves.
| Zone | Recommended level |
|---|---|
| Sunny Meadow | Lv 1+ |
| Muddy Lake | Lv 8+ |
| Dusty Desert | Lv 25+ |
| Web Caves | Lv 40+ |
Sunny Meadow is where a fresh egg respawns. Muddy Lake works well for a young Grasshopper. Save the Dusty Desert for a Jumping Spider getting close to its Level 28 adult form.
Combat, death and what reviving costs
Other players are the main threat. Your attack is Bite, bound to the left mouse button, and an “IN COMBAT” tag appears while you’re fighting. Some attacks leave you SLOWED. Players far above your level can catch you easily, and the server crowns the strongest player as KING BUG. Late-game bugs like a high-level Tarantula can kill a fresh Garden Spider almost instantly.
When you die, a “YOU WERE EATEN.” screen names your killer. It lists your kills, time survived, levels lost and the level you reached. The levels-lost figure is nearly your whole run. A Level 28 Jumping Spider loses 27 levels. You then have three options.
- REVIVE FOR FREE keeps all your levels, but it’s on a cooldown timer after use.
- REVIVE NOW (12 Robux) replaces the free option while that timer is running.
- RESPAWN (LV 1) starts the same bug over as an egg.
- CHANGE BUG and BUG TREE let you switch lines or buy an unlock first.
The free revive has a long cooldown. A countdown of around 50 minutes is normal before it comes back, so save it for a run you can’t afford to lose.
Teaming up with other players
Teams are the simplest defence for a small bug. Other players on your server can send you a team invite, which appears as a popup with ACCEPT and DECLINE buttons. When you accept, a “Joined … team” notice appears, and new members are announced as they join. You can also send friend requests from inside the game, so it’s easy to find the same players again next session.
From there, the loop repeats with bigger numbers. Each new bug line starts as an egg, asks for a higher level on the bug before it, and costs more coins. The Mosquito, at 1,800 coins after the Jumping Spider, shows how quickly those costs climb.
