Last Katydid

Every day, in recent days, I would venture out into the front yard with my camera to image the insects on the flowering lilies: the grasshoppers, the butterlies, and the adult katydids. Every night I would hear the chorouses and conversations of Katy Did, Katy Didn't. On July 27, 2013, I recorded this image of this adult katydid not realizing that this would be the last katydid I would see in the yard. I no longer hear the voices of the katydids at night. In past times I have seen and heard the katydids from July through October, and only after severe frosts would the katydid's voice become silenced. Has something odd happened here in this little corner of southern Columbia County, New York, USA? Or, is this phenomenon occurring elsewhere. Is this the precursor of worse times to come? Or, is this just a temporary condition in this little place in the world? I welcome any and all feedback.

For this image, I used my manual focus Tamron Adaptall-2 Model 52A SP70-210mm f3.5-4 CF Tele Macro Lens with attached Tamron Adaptall-2 Pentax KA Mount on Pentax K20D Camera, hand held, manually focused, Shake Reduction set to 200mm, ISO 400, f22, 1/180 sec, with fill-in flash from camera's built-in electronic flash. This is a full resolution Large JPEG and is Straight Out Of Camera (SOOC) and is without any post-processing, adjusting, editing, cropping, or re-sizing.
