Based on the remarks under the Nigricornis group, could this be O. forbesi?? Here's a copy of those comments: Regarding the difficulty in separating O. nigricornis from O. forbesi based on photographs: A gal who has done extensive studying of tree crickets (including song analysis, mating trials, and DNA sequencing) once wrote to me: In the eastern United States, I have found O. nigricornis, but not O. forbesi (in NJ and three sites in NY). In Ohio, I have found both O. forbesi and O. nigricornis in the same field, although the sites where I have found this have been in eastern Ohio (Akron and Canton). In central Ohio (Columbus area) and west from there, I have found O. forbesi but not O. nigricornis (OH, IL, WI, MI, IN, SD).
