These were seen in my butterfly puddle in March 2007 (a man made puddle in a plant saucer with soil, sand and a couple of stones big enough to stand a little way out of the water. It is meant to be a drinking place for butterflies and provide minerals that they need in dry weather – not that I have ever seen any land on a stone and drink from it! It is only 22cm in diameter and is 4cm deep but is amazing the amount of creatures this sustains. It can become very waterlogged but I never let it dry out.)
This looks very shrimp-ish, I have no idea what it is though it was tiny only a few millimeters and there were at least 6 of these.
I saw these things poking out the water during the day and thought it was a water worm. Then one night I saw one actually crawl out of the water on to a stone with lots legs it was about 15-20mm.
