The Swarming Sheargrub is a green sheargrub with red eyes, that in every way excluding size and color resembles a Female Sheargrub. Swarming Sheargrubs are known to follow Pikmin from a distance and can distract an entire squad as a result. They move around in swarms at high speed, one of the fastest of any known mandiblard. They have no form of offense but can move quickly, taking any attacking Pikmin with them. Once they come across any nectar, they will consume it and grow in size. They can also hide under plants, like Pikmin. Most swarms average seven individuals per group. Swarming Sheargrubs are only active during the day, emerging from under the ground at daybreak and returning to the point they initially emerged to burrow back underground at nightfall.
When they spot a salvageable object, such as a fruit, pellet, treasure, or carcass, they will jump and sit on top of it, weighing it down and thus making it require more Pikmin to carry. The larger a Swarming Sheargrub is, the more it will weigh.
While they can be an annoying hindrance, they are easily defeated like any other type of mandiblard. However, once a single member of a swarm is harmed, the rest will disperse and flee at very high speeds. It's advised to call all Pikmin back at this point, as they will attempt to chase the fleeing Sheargrubs, only to end up getting themselves lost.
