I am pretty sure I have both, lately here while doing a little raking I have been seeing a lot of very small very young water boatman in the vegetation. They are roughly 1/5 the size of an adult. Maybe I will try and get some pictures of them. I tossed one back in the water and it did swim right side up.

There is also a lot of other very small stuff moving around that I would need a magnifying glass to get a better look at, very small semi-transparent worm looking things. Maybe damsel fly larvea?
