I happened to find this huge black beetle pondering across my neighbors basement floor. She almost weighed as much as a full spool of quilting thread and was the size of the palm of my hand. She is a black rain beetle and is a rare find indeed. They take 13 years to mature and both sexes emerge just before rain and fall to mate then burrow underground again. The female does not fly only the male, so that was why she was walking in the basement. She was the neatest bug I have found yet. I set her outside to find a mate in the woods.
