Tree Cricket in the genus Oecanthus (best guess is the Western Tree Cricket, Oecanthus californicus). Male tree crickets “sing” using their two front wings. Chances are you’ve heard their loud chirp or trill before (listen here http://waynesword.palomar.edu/WS_30006.mp3). 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. Photo by Sadi Chadwick on 8/18/17 in Missoula, MT.
