Above: A Treesbane breaks into a group of Ephemerals nests
One of the most unique Predators of the Ephemerals is the Treesbane a housecat-sized genus of Linlolligo specialized in hunting Smaller prey. Most of the time Treesbanes spend their time hunting in the trees not much changed behaviorally from their ancestor, shy and elusive it feeds on generally small prey insects, grubs, and Blish eggs, and Squirdel young digging its prey out from their hiding places with a pair of elongated protrusions from its beak which can often create large wounds to appear on trees were they Treesbane stripe them of bark.
However, once every other year for a few months they are able to gorge themselves on Ephemeral eggs laid in slime-incrusted pits in the holes of trees which the Treesbane is excellent at breaking through with their beak as well as the numerous dying adults after the eggs are laid.
During these periods of gluttony, Treesbane may eat through several dozen nests although this hardly affects the overall population of the Ephemerals population with how great their numbers are. These periods of glut also create booms in the Treesbane population as the rush of easy protein encourages them to breed and the surplus of food results in larger litter sizes.
Much like Lynxs with rabbits once the supply of Ephemerals runs out it causes the population of Treesbane to drop dramatically as many of the newly independent young will not survive the suddenly much harsher environment they find themselves in. Treesbane population thus always fluctuates from much higher to lower than what would be normal for an animal of their size.
