Plotový Dědek

Rarity: Uncommon. The Plotový Dědek (Plotnicola moravica) is a remarkable arthropod endemic to the rural villages of the Moravian highlands, where it has evolved an extraordinary form of structural mimicry — it disguises itself as sections of wooden picket fencing. Adults reach 40–60 cm in length and possess elongated, flattened bodies composed of 12–16 rigid chitinous segments, each stained a deep umber-brown through dietary melanin synthesis derived from consuming rotting fence posts and bark. When stationary, the creature aligns its body vertically between genuine fence slats, extending rigid leg-plates that perfectly replicate the gaps and grain of weathered wood. Its six primary limbs are broad, flat, and textured with longitudinal ridges indistinguishable from wood grain at distances greater than one meter. The head is a narrow wedge tucked beneath the topmost segment, bearing two compound eyes that resemble rusty nail heads. It feeds primarily on the dense overgrowth that accumulates at fence bases — grasses, clover, and wildflowers — using a specialized rasping mandible hidden beneath its lowest body segment. Villagers in Rusava have long noted that certain fence sections seem to "migrate" overnight, and gardens bordered by old wooden fences occasionally show perfectly trimmed strips along the base while neighboring plots remain overgrown. The creature is crepuscular, most active at dawn and dusk, and communicates through low-frequency vibrations transmitted through the fence boards it clings to, creating a faint humming that locals attribute to wind. Its primary weakness is metal fencing — it cannot grip or mimic it, and the spread of modern materials has reduced its habitat significantly. A symbiotic relationship exists with local spiders, whose webs between slats provide the creature with supplemental protein in exchange for the stable vertical structure it offers. The scientific explanation for its uncanny mimicry lies in convergent evolution with stick insects (Phasmatodea), though Plotnicola diverged approximately 15 million years ago, developing rigid exoskeletal plates rather than flexible cylindrical bodies — an adaptation to the flat, planed surfaces of human-made structures, suggesting a surprisingly ancient relationship between this lineage and early Slavic woodworking traditions.
