Flitter

Flitters are somewhat common enemies in Donkey Kong Country 2: Diddy's Kong Quest, usually found in the swamps of Krem Quay. They are obviously modeled after real life dragonflies, though do not possess any kind of special attack besides flying.

Summary
Flitters usually just fly dormant where they are. They do not seek out the Kongs or appear to even notice them, so they're likely minor air grunts. Flitters, because of this, are considered one of the weakest enemies in the game, usually used for a platform for the Kongs to jump off of. They first appear in DKC2 and reappear in Donkey Kong Land 2.

Flitters return in DK: King of Swing. Only here, jumping simply doesn't defeat them, a charge attack is required to defeat them. Flitters return in DK Jungle Climber as well.

Trivia

 * Flitters were seen in a trailer for Donkey Kong Racing, making rumors that they were usable karts in the game.
 * All Flitters may be female due to the delicate eyelashes each one has in DKC2.
