If fortune tellers can tell a person's fortune by reading the lines on one's palm, or by studying the the dregs of a cup of tea, then what secrets might these seemingly meaningless squiggles hold?
These are the telltale meanderings of a tiny insect called a leaf miner. It lives inside the leaf, and as it chews its way around, it leaves these scribbling marks. I have long imagined what sort of meaning one could make of the lines.
OK, this one probably has more information than I would care to know.
