While the Nightreaper Piss Plants were mostly eating the tissue of pissflora, they would also occasionally eat the green pissbugs inhabiting them if they found them. These small critters provided a higher amount of nutrients compared to the tissue of the pissflora, so some populations of Nightreaper Piss Plant began to specifically hunt for them and thus gave rise to the Aleiatherista. The Aleiatherista is very similar to their ancestor during the day, being in a state of torpor while rooted to the ground as they gather sunlight through their wings from photosynthesis, only rousing themselves up if they are disturbed by something. It is only when darkness descends do they really begin to show their differences, as while they still wake up and uproot themselves to take off, they will act very different from that point onward. After they land on a Piss tree or any of its descendants, the Aleiatherista will bend their wings using their calcified skeleton and crawl around the surface. Three of the keratinized claws of their ancestor have come together on a distinct mobile "lobe" that allows them to twist in place somewhat so they can adjust their position as they climb. The root system has also developed keratinized tips on the end of each root, so they can help grab onto a piss tree to aid the Aleiatherista in climbing. The whole time they are climbing around, the Aleiatherista uses an extremely long "lobe" on their wings that supports two large claws to tap on the surface. As they do this, the bristles around their beak; which are also chemoreceptive to help them navigate as they fly around in the darkness, act like whiskers that pick up vibrations. This is important, since their prey lives within the tissues of piss trees and any vibrations may help the Aleiatherista in discovering their tunnel systems and if a particular green pissbug is close to the surface. If they detect one close to the surface, the Aleiatherista will use their beak to tear open a hole within the piss tree so they can then stick their long "tapping lobe" down to potentially fish out their prey. If the claws hook onto a victim, the Aleiatherista will yank it out of the burrow and snap it up within their beaks. While the majority of their prey consists of the green pissbug, certain species of Snufflers also make use of the tunnels and so they too also fall prey to the Aleiatherista on occasion. Only when the sun comes up, do the Aleiatherista fly off a piss tree and return to the ground, as they once again revert to being a harmless photosynthetic producer but now with a full meal being digested inside them.
