This is a Cicada, or as known to Halle B, the cat, PREY. Halle spotted her prey tonight on the patio, and tried to encourage it to come in through the screen door. I decided to go out onto the patio to water plants, and in the blink of an eye, Halle was out the door, grabbed her prey and made it back into the house with it......after some discussion about the advisibility of having a large green bug in the house, I was able to relocate it to the patio again.....where it waited patiently as I took its portrait. Since it might be an endangered species, I shut the glass door, and Halle had to be content with trying to get at her prey through the glass.
