User's notes

This was on a stick pulled from a farm dam. Probably about 10-12mm long. It moved by stretching out and then pulling its tail up ready to stretch out again, a bit like a leech, but otherwise seemed a lot like a flatworm. @turb could this be a freshwater flatworm? Or if not do you know what it could be?

Not a freshwater flatworm, nor a leech. Your specimen has setae (bristles), and specialized structures at one end that could be spiracles. I suspect that it could be a dipteran larvae of some sort, possibly a larval tipulid (Crane flies). Next time, when you find such beasties, place it in water then photograph it - this way it should reveal details difficult to see because of highlights when photographed out of water. Check out page 115 of The Waterbug Book.
