Hi all,

I've got tiny creatures on our waterfall. They're less than 1/4" in size.
Here's a pictu http://home.attbi.com/~pdewolf/Photos/creatures.jpg.

I wouldn't think that they're mosquito larvae because they seem to crawl
around on the rocks, rather than be suspended in the water (if they were,
the waterfall would take them down into the pond).

I know the picture doesn't have enough detail, but even guesses would be
greatly appreciated!

Paul
