Bugs

Bugs appear on planets of all types. They can be collected either by using a Bug Net, which will place them in a placeable jar in players inventory, or a Relocator which can release them to fly around again. Bugs captured using a net cannot be released from their jar again.

Most planet types have a unique set of bugs which can appear, with a few exceptions. To collect them all players will have to visit nearly every major biome.

The codex entry It's Not a Bug, It's a Creature also lists all ingame bugs.

Achievements

There are two Steam achievements tied to collecting bugs with a Bug Net. Bugs captured with a Relocator won't count toward achievement progress.

The first, Bug Tracker, is awarded after players catch their first bug. The second, Bug Free, is awarded after capturing all 42 bug types.

	Name	Description	Requirements
	Bug Tracker	Capture your first bug with a bug net. Esther would be proud.	Collect a bug using a bug net.
	Bug Free	Catch 42 unique bugs. Give them all funny names.	Collect 42 bugs using a bug net.

Bugs Collection

After a bug is captured using a Bug Net it's registered into the Collections Library window. Bugs caught using a Relocator won't count toward collection progress.

After capturing a new bug a notification will appear at the bottom of the screen, announcing they've completed a collection entry. That bug jar will then appear inside the Collections Library window, with a description which appears when moused over.

Since the requirements for the Bugs collection and the achievement 'Bug Free' are the same it's an easy way to track progress towards the achievement.

Some bugs have time restrictions when spawning and will only be seen during the day or night.

Below is the full listing of capturable bugs, along with their collection number.
