Iridescent Flint Beetle

The Iridescent Flint Beetle is harmless to Pikmin, and instead runs around unpredictably. When a Pikmin is thrown directly on top of it, it flips over and drops a useful object or item, such as a pellet or a drop of spray. Pikmin attacking from the ground cannot harm it. This enemy spends most of the time underground, only surfacing when a leader comes near, and it will return to the ground after some time has passed or after it has been hit enough times.

In Pikmin Eco
The Iridescent Flint Beetle is a harmless enemy appearing in Pikmin Eco, and one of the few enemies that are found in every aboveground area in the game. It scurries around at high speeds and drops nectar and pellets when struck from above, so although difficult to hit it is beneficial to try and attack it.
