Unmarked Spectralid

Unmarked Spectralids are insects in Pikmin 2. They resemble small butterflies, colored either red, yellow, or purple; in the Piklopedia, blue and green variants are also, rarely, seen. They are one of the series' harmless enemies, having absolutely no means of attack. They are located in specific patches of plants and appear upon being disturbed, leaving the area's boundaries not long after. Their color indicates what they drop, being either ultra-spicy spray, ultra-bitter spray or a pool of nectar.

The only area above ground they appear in is the Awakening Wood, one group hidden in a Margaret near the Sunseed Berry, and another in a nearby Figwort (next to the bridge there); red and purple Spectralids do not appear above ground, and can only be found (along with more yellow Spectralids) in "rest sublevels" of certain caves. Usually underground, they are found in clusters of 20 or more. These creatures are so delicate that, upon being petrified, they will fall down to the ground and crumble.

Olimar's Notes
When strolling through the forests of this planet, clouds of these creatures are seen dancing overhead. Like flower petals drifting in the breeze, the sight of flitterbies dancing in the lush green undergrowth is unforgettable. Flitterbie collectors drool over specimen sample boxes lined up in order, highlighting the slight color graduation changes from blue to red to yellow. Such items tend to fetch particularly high prices at auctions.

Louie's Notes
Spectralids don't provide a lot of meat, but the exquisitely elegant wings are surprisingly tasty, particularly when expertly prepared with a sweet candied glaze.

How to kill
Throw Pikmin rapidly into the air in all directions in an attempt to knock them down, or spray a large group with an ultra-bitter spray if you're short on Pikmin. The latter is only really worth it if red- or blue-colored Spectralids are present in the swarm.

Pikmin:Redemption
There are black and orange colors; and green and blue variants are in the game as actual enemies instead of only in the piklopedia. Black drop Ultra Poison Spray; Orange drop Pikmin Essence; Green drop Ultra Sour Spray; and Blue drop Growth Hormone.
