Wall harvestman
Opilio parietinus
The wall harvestman (Opilio parietinus) is a species of arachnid belonging to the order Opiliones, commonly found on building walls, fences, and near human habitats. It features an oval, grayish-brown body measuring up to 8.5 mm and exceptionally long, thread-like legs that can span several centimeters. Although frequently mistaken for a spider, it belongs to a distinct group. It does not spin webs and lacks venom glands, making it entirely harmless to humans and pets. Mostly active at night, it acts as a natural cleaner by preying on small insects, mites, and feeding on decomposing organic waste.
