Witnesses

Do you remember those lines your parents meticulously drew on a wall, marking your height year after year? Those lines moved higher with each passing year. The grooves you see in the wood and under the bark can be viewed in the same way.

These are the hallways chewed by insect larvae, whose mother laid eggs here. Each twisting corridor is a record of the larva’s life, a testament to its growth as it consumed the wood.

They never got in each other’s way; their passages just grew wider and wider. Can you find the direction of their journey?

Just like the lines on a wall, the width of each hallway is a direct witness to the larva’s growth.
