I've had a bucket of water outside for my dog. He stays indoors but sometimes is outside with me, and I put it out there in case I ever forgot him outside in our yard. Anyhow, I came across this insect in it several days ago. I saw it floating there and thought it was dead. Then today--several days later--I noticed it was swimming in the water (well not swimming, but moving a bit). I am squeemish about these things so I got my sister to take it out with a broom and amazingly it walked around on the ground as if nothing had happened. We debated about whether to kill it or not. Both of us are vegetarians and don't like killing things. But we were worried it might be a cockroach which I guess have diseases. The reason to be concerned is that this water bucket was right next to the door of our house. We eventually decided to sweep it into the grass. FYI: it was in total about two inches long, maybe a little more. For future reference, does anyone know what it is?
