What a wonderful website!
I have been finding one of these bugs in my pool or in the grass almost every day. Last night one flew into my pool. I think they are around 3″ long. The underside has horizontal stripes and is brownish colored and fat. Is this a cockroach?

This is a Longicorn in the subfamily Prioninae, and even though your image lacks the kind of clarity we prefer for a species identification, based on your location and the time of year, we would bet that this is a Palo Verde Borer, Derobrachus hovorei. More information on the Palo Verde Borer can be found on BugGuide.
