This male was ID'd by song to be O. forbesi by Dr. Thomas J. Walker. When taped outdoors with a temperature in the 80's, the song was very rapid. According to Dr. Walker: "The tree cricket calling on catmint in the 80’s was producing 82 sound pulses per second at a carrier frequency of 4.6 KHz. Checking Fig. 12 in p. 781 in my 1963 paper on the nigricornis group, your cricket is definitely the fast-trilling form or O. nigricornis (i.e., Oecanthus forbesi)." I will be taping this species next season under controlled temperature conditions in order for Dr. Walker to do some more extensive analysis.
