Adult Euborellia annulipes are typically dark brown, and 10 mm (0.4 in) to 25 mm (1.0 in) in length.[4] It is a wingless species, and like most earwigs, the females are larger than the males. Their legs are a pale brown color, and have a noticeable dark band around the middle of the femur, or occasionally the tibia, hence their common name.[1] Their antenna generally have sixteen segments, although other numbers are possible.[1]
