As I was calmly walking around my garden, something strange caught my attention. A long, winding shape lay on the ground, like an abandoned rope, left there by someone. Intrigued, I first assumed it was just a piece of string.

But as I got closer, a sudden thought chilled me to the bone: “What if it’s a snake?”
My heart started pounding. What had seemed harmless just a moment ago now felt ominous…

Caught between panic and curiosity, I quickly grabbed my phone and snapped a picture.

With adrenaline surging, I began to move closer, step by step. Each movement felt heavy, each meter I walked increased the tension. What if it really was dangerous? The thought sent a shiver down my spine.

Then, once I got close enough to make out the details, I was stunned. What I saw was nothing like what I had imagined…

It was neither a rope… nor a snake.

What lay before me was a living column — a slow but perfectly ordered procession of around 150 caterpillars!

Yes, I counted them one by one, unable to believe my eyes.

They were marching in a straight line, tightly packed, as if following some invisible leader. The sight was both fascinating and bewildering. Never in my life would I have imagined that such a phenomenon could exist… let alone right there, in my own backyard.

Where were they going? Why were there so many?

These questions keep running through my mind.

Some say caterpillars move in groups to deter predators. Others believe it helps them find food more easily. Maybe it’s simply a strategy to conserve energy: the ones at the front make way for the others to follow more easily.

But where exactly did they come from?
And most of all… where were they going?

A total mystery.
