In the past week or so I have been hearing extremly loud clicking sounds coming out of the trees around base. I thought they were either katydids or cicadas. It has been incredibly hot, hitting around 117 degrees F for several days in a row. The critters making the sounds didn't seem to mind the scorching temperatures.
Several days ago I was walking back to my trailer at about 2 AM, the temperature was still in the nineties. In one Eucalyptus tree next to a portable construction light had what sounded like dozens of the clicking critters. After a second of searching I found the culprit, small green cicadas with blue eyes! The color was incredible and contrasted dramatically with the dust covered leaves. I caught a few and went back to my building to get my camera. The cicadas buzzed angrily like little toy noisemakers in my hands. Two soldiers smoking outside didn't know what to make of the noise when I walked up.
When I went back to the tree there were cicadas buzzing around the construction light and bats circling catching insects. I have not seen or heard any large aggregation of cicadas since. I'm wondering if there was simply a large emergence and then dispersion.
