Unmarked Spectralids (or Unmarked Spectralid, see below; サンショクシジミ?, lit.: "Tricolored Clam") is an insect in Pikmin 2. They resemble small butterflies, colored either red, yellow, or purple. They are one of the harmless enemies in the Pikmin series, having absolutely no means of attack, and do nothing but flutter around. They are located in specific patches of plants and appear upon being disturbed, though in some caves they are readily visible. They will leave the area's boundaries some time after they appear. Their color indicates what they drop when killed, being either a drop of ultra-spicy spray (red), ultra-bitter spray (purple) or nectar (yellow). Underground, they only have a 20% chance of dropping these contents. These creatures are so delicate that, if touched by a single Pikmin, they will instantly collapse and die. Upon being petrified, they will fall down to the ground and crumble; in the Piklopedia, however, they will remain intact.
The only area aboveground they appear in is the Awakening Wood, with 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 found in clusters of 20 or more. On the Awakening Wood, only four of them appear together in each spot.
“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 gradation changes from blue to red to yellow. Such items fetch particularly high prices at auction.”
“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.”
Unmarked Spectralids seem to not fear creatures that are idling. If there is a Mamuta in the same level as a swarm of Unmarked Spectralids, it is possible to spot some of the Spectralids land on the creature as it idles. In addition, after both the Unmarked Spectralids and the Red, Orange, and Hairy Bulborbs have been added to the in-game Piklopedia, the Spectralids can be seen flying around the former two bulborbs in their respective Piklopedia files.
These merely flutter about without waking up the bulborb, occasionally landing on it, but due to the way collisions work in the game they are unreasonably strong, commonly pushing the bulborb around, sometimes even shoving it out of the regular map boundaries.
They cannot be damaged with punches in any way, not even while petrified or resting atop a Mamuta.
