Hairy FlywormsThe Eyed Flyworm was the last flying creature left on the planet, having avoided a UVB-irradiated demise by happening to reside in a cave. When the world outside transformed into one where the sun was a deadly laser, some of its descendants which emerged from the cave rapidly developed nocturnal adaptations, producing the
hairy flyworms. Like a Terran moth,
a coat of chitinous setae holds in the heat they generate through flight, allowing them to stay active in the cold of night. Further,
their “sticky pad” feet have extended into functional, unsclerotised hydrostatic legs, allowing them to move quickly to avoid predators or sunlight when exposed. Hiding under rocks and soil by day and flying about in search of food by night,
these fuzzy little wingworms soon spread all over the planet, taking over some of the niches that had been vacated by the extinction of all other flying creatures.

The most basal and instantly prolific group of hairy flyworms are the
fuzzflies (
Pellimuscavermis spp.). Staying true to their ancestral niche, with all the dead organisms quite literally covering the ground,
these flying scavengers diversified into over a thousand species, ranging from tiny creatures only a millimeter in length to “giant” inch-long forms. They utilize chitinous bristles on their tongues to tear into their meals. They are present in nearly all terrestrial biomes, and
at dusk they will swarm in large numbers to the carcasses of fauna which were stranded and perished in the burning daylight.

Another basal group of the hairy flyworms is the
puckbugs (
Basimuscavermis spp.), which have modified their mouths for sucking.
Puckbugs primarily consume sap, though some species are not impartial to drinking blood. Having diversified into over a thousand species, much like their close cousins the fuzzflies, the puckbugs are cosmopolitan and present in nearly every terrestrial biome. The largest species are only around one centimeter long, the majority being between 3 and 5 millimeters.

The
lampredates (
Dracomuscavermis spp.) are a far more derived variety of hairy flyworms.
They have gained an additional pair of eyes on their cephalic segment, allowing them to easily pursue and prey on other flyworms.
Their mouths bear chitinous spines, which are similar to the oral ring of their distant ancestors as well as their cousins the saucebacks,
but the spines are immobile and not homologous with the teeth their ancestors lost; they can be likened to the keratinous “teeth'' found in the mouths of some Terran birds in this respect.
Their first and second pairs of wings flap together, as do their third and fourth, allowing them to fly with less energy compared to other flyworms. They can reach up to about an inch (2.5 cm) in length, though the majority of species are smaller, generally in the 4-8 mm range. Similar to their cousins, they are cosmopolitan, being present in nearly every terrestrial biome.
