18-Scorpii-4 Fauna: Avian Hexapods

The hexapods of 18Scorpii are the most diverse macrofauna on the planet, and one of these groups has become completely dominant in the aerial environments of this world.
This group has been designated with the code: "ACL" for "Aves-Chiroptera-Lepidoptera."
This somewhat unwieldy code name is the result of a simplified explanation of the anatomy of the animals that make up this clade. Indeed, this group of (mostly) flying animals possesses characteristics reminiscent of the three animal groups that make up its code name.
The first group has been nicknamed "Beebat," adapted to nocturnal hunting, like ground bats. These animals are easily recognizable by their hand-like wings and feathered ears. Their name also refers to bees, due to their social behavior and the fact that their stylus is always shaped like a very fine point (like a stinger).
The second group was nicknamed "Mothbird" for ease of nomenclature… because even though these flying animals don't always have colorful or patterned wings reminiscent of butterflies or moths, this nickname helps maintain the "insectoid" appearance of this fauna. This group was the first to be studied and therefore served as a reference for the rest of the phylogeny of "ACL".
The last group is the only one that does not possess the ability to fly, seemingly having lost it during their evolution into terrestrial predators. This group, simply nicknamed "Raptor," remains a true ACL due to its anatomical characteristics, such as the presence of small wings on the third pair of legs, which here seem to have a function in communication or display between individuals of the same species.
