The journey of 1000 miles...
...starts with 100 steps. Or there abouts. A single step seems too restrictive for this fellow. I don't know why this caterpillar decided to cross the water lettuce to get to the other side of the pond but it was chugging right along.Up one leaf, down the next, repeat. I have to assume that frogs don't eat caterpillars as they didn't bother him. I don't know the type of caterpillar so I can't give you any scientific stuff.
