For accuracy in the mapping of species....
...this is being moved to the forbes vs nigricornis page. These two species cannot be determined from one another on photos. Both Forbes' and Black-horned can have a great deal of black on the antennae, head, pronotum and limbs.

From previous work by a researcher who collected and recorded the song of many individuals throughout many states, it is generally accepted that Forbes' occurs west of Ohio and Black-horned occurs east of Ohio. Both species occur in Ohio.

States close to Ohio are difficult for identification to species.

Thank you!
I've gone out looking for more tree crickets and while I can hear them, it's very difficult to see them. This pair was very cooperative.

Moved
Moved from Common Tree Crickets.

I agree. Although at times it is difficult to separate O. nigricornis from O. forbesi -- given the deep black limbs of this pair, I believe Black-horned tree crickets is a good call.
