Over the past week I have repeatedly seen this reduviid at the top of large clumps of dead grass. What's a reduviid doing on dead grass, where prey is not likely to occur? As I went to catch it for a photo, it raised its front two legs up and to the sides, exactly as I'm used to seeing salticids do in threat or territorial displays. I have not been able to get it to repeat the behavior, but I still have it in a container for now.
