The Violet Follow-wing is a violet, arrow-shaped, scavenging flyer from Darwin IV. They were first thoroughly observed in Vallis Przewalski in Planitia Borealis one autumn day in 2358, during the First Darwinian Expedition.

Traveling in small flights, these two-meter-long flyers bank and turn with startling precision.

Retinues of Follow-wings will follow predators like Skewers when a hunt has commenced. When Skewers dive in front of Follow-wings, instantly they slow and fall in behind their immense cousins, veering and banking as the larger flyers do.

After a prey animal (such as a Symet) has been killed and is impaled on a Skewer's lance, the scavenging Follow-wings are in a frenzy, darting forward to nip at the slaughtered prey animal with their vertically hinged jaws. Bits of flesh fall from the killed prey animal to be snapped up by other Follow-wings.

The soaring Skewers take absolutely no notice of the scavengers, absorbed as they are in sucking a carcass dry. A few minutes later, the Follow-wings are presented with a fluidless husk as the Skewer lets it fall. Without hesitation the scavengers peel off and dive after their meal, making so many passes at the body that little more than bones hit the ground.
