Bug Evolution is a survival-based Roblox experience that follows the rule of the jungle. You start as a tiny spider, consuming food and creatures like moths, scorpions, and caterpillars to gain Coins and unlock insects in the evolution tree. Each evolution lets you take control of a different bug with higher stats. Whenever you’re killed, you lose levels and are given the choice to restart or revive.
Given that there are dozens of creatures to purchase, evolve into, or acquire as rewards, finding the best insect for your playstyle can get tricky. Avoid the entire trial and error by reading this updated Bug Evolution tier list, so you know exactly which insects to target and skip.
Ranking all bugs in Bug Evolution
As of the Giant Mosquito update, there are 39 insects in Bug Evolution. Most of the top-tier ones are limited to events or packs that require Robux to be purchased.
All bugs in this game have been categorized into four tiers, according to their stat grades. Equip the S-tier or A-tier insects and quickly level them up by eating food or creatures before hunting other players on the map. If you require a more peaceful grinding session, invite others to your party.
Tier S
The best insects belong to this tier. Most are available for a limited time, so make sure to obtain them as soon as possible. Void Mosquito is a reward from the Void Spinner gacha that requires Void Credits.
