Beetles are highly aggressive insects found in the Chozo Ruins and Tallon Overworld of Tallon IV. They burrow themselves into the ground and attack anything that comes near them. While underground, Samus can detect the Beetles' heat signature with the Thermal Visor.
 Ethology and Morphology
Beetles are extremely social and typically attack in large groups. One particularly large group attacks Samus in the Ruined Shrine of the Chozo Ruins before she acquires the Morph Ball. They nest and incubate their young underground, and will put their lives on the line to protect their home and each other. When intruders disturb the nest but remain out of reach, Beetles will put on territorial displays including hopping in place, waving their decorative fins, growling, and barking from a distance.

Plated Beetles are larger than an average Beetle and have a significantly harder carapace that can deflect Beam and concussive weapons. Its enlarged red abdomen is its weak point. Unlike regular Beetles, Plated Beetles appear largely solitary.
 Ice Beetle

A variant native to Phendrana Drifts, Ice Beetles are a stronger variant covered in a hard ice shell that is susceptible to heat. Ice Beetles prefer to travel in much smaller groups than regular Beetles, usually pairs.
 Beetle Blast
In Metroid Prime Pinball, Beetles star in their own mini game called Beetle Blast. Here, much like many other mini games, Samus's objective is to eliminate all or as many enemies as she can. Samus's Morph Ball stops in front of the flippers, Samus exits Morph Ball mode and points to shoot at burrowing Beetles. The creatures will burrow upwards and out of the ground, swarming toward Samus while she shoots them out with her Power Beam.
