Female Sheargrubs are one of the weakest enemies in the Pikmin Series. They are apart of the Mandiblard Family. The female sheargrub can't harm pikmin in any way, while the male kills pikmin. These are in Pikmin 1 and Pikmin 2. The Males are also a little darker than the females. Sheargrubs can eat bridges that pikmin make, making them annoying.
