The Scarpanid family is a family of insects that were originally ground dwellers, but have since evolved flight by converting their antennas to wings. Several species of Scarpanids exist, although research regarding the family has since stagnated. Five species of Scarpanids are known currently.
The Swooping Snitchbug is a creature present in all three Pikmin games. They are legless, round, flying insects that have evolved wing-like antennae as a means of locomotion. They attack by swooping down and grabbing prey. After carrying them for a few seconds, they violently throw them toward the ground. This action would harm most prey, whereas Pikmin are simply replanted and reverted to their original leaf stage. Snitchbugs can be weighed down by throwing many Pikmin (or at least one Purple Pikmin) onto their body, causing them to crash to the ground and making them susceptible to attack. In Pikmin 3, throwing a Rock Pikmin at the creature will cause it to fall to the ground immediately as well. Also in Pikmin 3, they replace the role of another Scarpanid species from Pikmin 2, the Bumbling Snitchbug, by gaining the ability to grab captains as well as Pikmin.
The Bumbling Snitchbug is a creature exclusive to Pikmin 2. It closely resembles the Swooping Snitchbug in appearance and behavior, though it possesses more body mass. Instead of picking up Pikmin, it will only target the Captains, and eventually hurl them into the ground; however, they will not be "planted". Captured leaders may struggle to free themselves by rotating the analog stick or have a second leader throw Pikmin to combat the enemy. Weighing the bug down will cause it to crash into the ground, where it is easily overwhelmed.
Main article: Coppeller
The Coppeller is a creature in Hey! Pikmin. This creature flies in groups across the screen, carrying Sparklium or Pikmin. Coppellers can't kill Pikmin, not counting any Pikmin they carry. It can be defeated by throwing one Pikmin at it, causing it to drop its cargo.
Main article: Spiny Coppeller
The Spiny Coppeller is a variation of the Coppeller in Hey! Pikmin. This creature has spines, but can no longer carry Sparklium seeds or Pikmin. Due to their spikes, they cannot be killed, and must be avoided.
Main article: Muggonfly
The Muggonfly is a creature in Hey! Pikmin, and only appears once in Area 8-D, Olimar's Madcap Ride. It can't be killed, nor can it hurt you, but carries many Sparklium seeds when it appears. When you reach the area it appears in, collect as much Sparklium as you can before it flies away.
