Unpleasant and sticky, Shartbeetles are the living byproduct of Muckpincers. A Muckpincer is exactly what it sounds like, a widely-varied species of footlong earwig with twenty eyes and mandibles the size of ploughshares. Feeding off of a forest’s soupy decay, Muckpincers gorge themselves to the point of shattering their own internally armored bowels. This incredibly unpleasant process jars loose unique parasites within the Muckpincer, which in turn erupt like boils from the Muckpincer’s glassy, black cloaca.
These parasites are Shartbeetles. They are mean, anxious insects prone to cannibalism and resistant to the elements. Not unlike roaches they are nearly functionally immortal and will persist like fidgety ghosts, pooling in great numbers at the feet of dying trees.
Despite their revolting life cycles and menacing appearance, both creatures are harmless and feed entirely on rotten leaves, sticks, and various fetid flotsam.
