Eastern harvestman (Leiobunum vittatum) is a common, large, easily recognized harvestman. It occurs in the United States and southern Canada from the east coast to the Great Plains. In Minnesota it is common in the wooded eastern region, uncommon in the western prairie region.
The body is golden yellow to dark reddish-brown with a large, distinct, dark figure on the upper side. In summer the figure contrasts sharply with the lighter background. As the season progresses both sexes become progressively darker. By mid-fall they can be almost black.
The legs are extremely long and slender. The patella is short and dark. There is also a dark band at the outer end of the tibia. On the female the legs are light brown with contrasting dark rings. On the male the legs are dark brown and less contrasting.
