I'm moving these to Texas tree cricket....
Since there seems to be quite a bit of yellow tint. A brown form of O. californicus would not be yellow - it would be pale brown.

Both species probably occur in the area, so one can't say with 100% certainty.

 
O. texensis confirmed by recording
The recording you provided by email was analyzed using AVS Audio Editor, and confirms that your singing male tree cricket in a temperature of 84 Fahrenheit is Oecanthus texensis.

The pulse rate for 1 second = 44. This is a good match for the graphs provided on Singing Insects of North America (SINA). /http://entomology.ifas.ufl.edu/walker/buzz/577a.htm -- see Song data excel spreadsheet.

If this were O. californicus, the pulse rate at 84 Fahrenheit (28.8 C) would be over 60 pulses per second.

 
Fascinating!
Thank you Nancy for analyzing this recording and posting the results. Kudos to you for your dedication and valuable work.

 
I have been looking for the elusive
Oecanthus californicus in El Paso without success so far. Maybe I get lucky one of these days. Thank you Nancy!
