Odd insect or item found in a pond, there appeared to be two types, one was completely see through and the other had a pattern in it. The size can be gauged by the tadpoles alongside, and they were definately moving around.
These are pond snail eggs. When they are first laid they are uniform in colour but as the baby snails develop they appear to develop a pattern. The eggs are suspended in jelly, like frog spawn, and move with water movement.
