A close-up, vertical photograph depicts a dark brown, bristly caterpillar positioned on a textured, reddish-brown wall surface. The caterpillar is approximately 4-5 centimeters in length, densely covered with long, light-colored bristles that extend outward from its body. It is oriented vertically, with its anterior end towards the top of the frame. A prominent vertical crack runs through the center of the wall surface, with the caterpillar positioned directly adjacent to it on the right side. The wall exhibits areas of green moss or algae growth, particularly on the left side of the crack, and irregular white deposits or growths are visible on the right side. No human subjects or discernible actions are present. The environment is an outdoor wall setting located in Narayi, Nigeria.
