Female Sheargrub

Female Sheargrubs, unlike the members of the opposing gender, are scavengers and do not attack leaders or Pikmin but will still chase them. Their behavior, along with their light pink color and relatively small jaws, is the most distinctive difference between males and females of the species. As with Male Sheargrubs, however, they destroy stick bridges. Female Sheargrubs regenerate health when they are underground, just like Male Sheargrubs, and can fully heal themselves in seconds. When their health is very low, they will bury themselves and recover, and when they regenerate enough health, they emerge and continue their chase if there are leaders or Pikmin nearby.

Olimar's notes

 * "The males of this species are purple and black creatures with tapered mouths, while the females are lighter in color and lack an armored exoskeleton. As with most mandiblards, these creatures have regressed to the point where they have lost both legs and wings. They can be seen crawling around on the ground and are believed to feed on the vegetable extracts from the congealed fluids of expired Pikmin."

Louie's notes

 * "For an unforgettable quiche, slice this creature up and mix with four eggs, two vine-ripened tomatoes, dried zucchini, and generous handfuls of feta and swiss. Bake until crusty and golden. This beast is most flavorable if caught and cooked just after laying its eggs."

Pikmin: Redemption
In PR these are more evolved and can fly for brief periods. They are still cannon fodder, though.

Pikmin: The Bulblaxian War
Female sheargrubs reappear in Pikmin: The Bulblaxian War, and are as easy as before. They appear so far in The Temple of Ice.

Olimar's notes

 * "This is the female of a species that prey on Pikmin. Only males have the nutrients to develop a harder jaw, so the females' squishy mandibles don't help it kill Pikmin."

Ship's notes

 * "Hmmm... I wonder what it would be like to be a Female Sheargrub: "HAHA! DIE PIKMIN!" Squish... squish... squish... "WHY WON'T YOU DIE?!? HAAAAAAAAAAAAX!!!"

Tike's notes

 * "These creatures have a thing for birth rates. Although according to my analysis, they give birth to males a lot more often than females. I wonder why this is the case? Despite the facts, it seems that females have a larger life span then the males. I actually believe that the white color is from aging. I checked and every male is mainly younger. Ermm who knows?"

Alice's notes

 * "What delicate and polite creatures. Though they love to eat wood. Actually, in truth, they only eat wood. I know I'm picky, but come on they're plenty of soft food to eat... wait they can chow wood, but... Never mind. They tend to keep very friendly intensions with the males, but I do wish the males... you know could give the females more respect."

Captain Pikmin's notes

 * "I actually feel bad for killing these helpless creatures... they sadly are that easy."

Pikmin Forever
In Pikmin Forever, they usually appear alongside the Male Sheargrub. Female sheargrubs are graphically and behaviorally advanced. It gives off a very dim, pinkish glow in dark areas. Although they are unable to harm Pikmin, they will seek out nearby nectar to sip up. In fact, early in the day, Female Sheargrubs may be witnessed roaming the area in search of naturally-occurring nectar near nectar weeds and other vegetation. They can be brought above ground forcefully by a Purple Pikmin if they are thrown onto the spot where they reside. They can only burrow in soft places like dirt. If killed, they will drop 0-2 small droplets of nectar, which flowers 2 Pikmin each.

Pikmin: Dimensional Breach
Female Sheargrubs reappear alongside their male, winged, and swarming cousins in Dimensional Breach. They are still unable to harm Pikmin, but they will deconstruct bridges and climbing sticks. After obtaining his special upgrade, Louie can control them and use them to build the very things they exist to destroy.

Sagittarius' notes

 * "The female and male Sheargrubs should be kept together at any cost. Males will feed the females over time, so don't worry. Sheargrubs should be placed in a glass tank, not unlike an ant farm, where one can see the distinctive network of subterranean tunnels that these creatures dig out."

Libra's notes

 * "Meh. Nothing much to speak of. The color does make for good shoulder pads for snowboarders, but that's about all I can think of."

Charlie's notes

 * "They aren't hostile at all and go down with one Pikmin. I recommend only destroying them if they try to chew on a bridge or you need a Pikmin boost."

Derrick's notes

 * "The perfect test subjects for my experiments, Female Sheargrubs don't fight back, can't flee through a steel floor, and are completely helpless against my tests without their husbands to back them up."
