I saw a program once and knew what came out of these little eggs on a string.
Although I have forgotten the creature that laid them, I am aware of the reasons behind the structure....those long, and slippery, strands are a perfect way to stop predators reaching those tasty little packages.
Have a look at the photo below. My first impression was that they are from a butterfly, though I am not so sure....
Blog comments are always welcome.
Some help in solving this one? :)
