This crayfish is gray with numerous greenish-black speckles and blotches on the pincers, carapace and abdomen. A pair of large blotches are present near the back of the head, and another pair occur near the junction of the carapace and abdomen. The fingers often have conspicuous cream-yellow tips. The carapace is not separated at its middle by a space (areola). The gray-speckled crayfish is the only common Orconectes in the southeastern lowlands. Other typical crayfish of the region have longer, more slender pincers, and none have the pattern of dark paired blotches described above.
