If you find a green tree cricket in North America, you can be certain it is in the genus Oecanthus. Most can be identified to species by examining the markings on the underside of the first two antennal segments. Male tree crickets “sing” using their two front wings. A sharp edge or “scraper” is located on the upper surface of the lower wing and is rubbed against a row of bumps known as the “file” on the underside of the upper wing (view a scraper and file here). Chances are you’ve heard their loud chirp or trill before. Males have a cavity on their upper back, sometimes called a “honey pot.” They secrete a liquid into the pot that attracts females, which feed upon the liquid. This perfectly positions the female for mating.
