These markings match Forbes' tree cricket
Several species in the nigricornis group in the Midwest are difficult to separate based on antennal markings: O. forbesi vs O. nigricornis vs O. argentinus.

Based on the location in Wisconsin, this is being moved to O. forbesi.

O. argentinus has not yet been documented in Wisconsin, and O. nigricornis is questionable. O. forbesi and O. nigricornis can look identical, they can only be separated by counting the pulses in the males song at a known temperature.
