Just this morning, after nearly 24 hours of a gentle rain, one of these creatures was found on our kitchen floor near the back door. The dog, having just come back inside, must have transported it on his foot/leg. Thank goodness for the internet! I was concerned, obviously, having a three year old and a crawling infant, that we had some strange, possibly dangerous, species of snake or worm invading our home. That triangular shaped head set off alarms in my head!
