Moth

From Halopedia, the Halo wiki

A moth on the level 343 Guilty Spark.

"Moths" were a type of insect encountered in the swamps near the Flood containment facility on Alpha Halo. They, along with the Sea Worms in the waters off the Silent Cartographer, are the only known species indigenous to Installation 04.

Gameplay

In Halo: Combat Evolved, the moths are harmless to the Covenant and Humans alike and have no interaction with the player.

Along with the sea worms found on The Silent Cartographer moths are the only animals found in the Halo: Combat Evolved, although the calls of various other creatures can be heard at certain points throughout the game.
