Yellow Spectralids

Yellow Spectralids  are small butterfly-like creatures in Pikmin 3 and Pikmin 4. They have yellow wings, very fuzzy, white bodies, purple eyes and two small feet they use to stand on things. In Pikmin 3 they will fly around at any height and land on almost any surface, from flowers to Bulborbs. In this game they also function very much like yellow Unmarked Spectralids from, in that they leave a drop of nectar when killed. Compared to the other flutterbies in Pikmin 3, Yellow Spectralids have yellow wings with a black "outline", and a black dot exclusive to the bottom wings.

Behavior
Yellow Spectralids may be seen on the ground, nearby flowers, or the back of a sleeping Bulborb, but in all cases, when a leader or Pikmin approaches them, they will fly away. They will flutter around aimlessly in the air, and while doing so they are difficult to reach. After the leader moves a considerable distance away from the Spectralids, it will return within 10 seconds.

Strategy
A direct hit from any type of Pikmin will instantly defeat a Yellow Spectralids. Winged Pikmin are, however, the best option, as they will give chase if the creature tries to fly off.

Trivia
