For centuries, scientists were baffled by one of nature’s greatest mysteries—how could swarms of locusts travel across vast oceans when their tiny bodies couldn’t possibly store enough energy for the journey?
Some experts speculated that they rested on floating debris or even the carcasses of whales, taking breaks as they hopped their way across the waves. But the real answer? It’s far more disturbing than anyone expected.
Locusts don’t stop to rest. They eat each other while flying.
Yes, these seemingly mindless insects turn to mid-air cannibalism, devouring their fellow travelers to fuel their relentless march forward. This revelation paints a terrifying new picture of locust swarms—not just as destructive forces of nature, but as aerial feeding frenzies where the weak become the fuel for the strong.
Let’s dive into the bizarre and unsettling reality of how cannibalism keeps locust swarms alive.
1. The Mystery of the Ocean-Crossing Locusts
For decades, scientists struggled to explain how swarms of locusts could migrate across hundreds—or even thousands—of miles of open ocean.
? The problem:
- Locusts can’t store enough fat or glycogen to sustain long flights.
- Unlike birds, they lack the ability to glide or take breaks mid-air.
- Floating on the ocean seemed implausible since most locusts would drown.
With no clear explanation, some scientists theorized that locusts might briefly land on ocean debris, driftwood, or even dead whales to rest—but there was never any solid evidence to support this idea.
The truth would turn out to be far more brutal.
2. The Shocking Discovery: Cannibalism in the Skies
Researchers eventually realized that locusts had a gruesome solution to their energy problem: they feed on each other in mid-flight.
? How it works:
- When a locust starts running out of energy, it latches onto another locust.
- It bites into the softer parts of its victim’s body—often the wings or abdomen.
- As the weaker locust is eaten alive, the stronger one gains enough energy to keep flying.
This means that a locust swarm isn’t just a coordinated mass migration—it’s a violent, airborne battle for survival where only the strongest (and fastest) locusts make it to their destination.
? Fun Fact:
Locust swarms can contain billions of individuals, stretching for miles. That’s a whole flying buffet of cannibals soaring through the sky!
3. Why Locusts Turn to Cannibalism
Cannibalism isn’t new for locusts—it’s actually built into their survival strategy.
? Locusts eat each other for several reasons:
- To survive starvation: When food is scarce, locusts will gladly devour their neighbors.
- To keep moving: If a locust hesitates or slows down, others attack from behind.
- To avoid being eaten: Faster locusts stay ahead, while weaker ones become lunch for their own swarm.
This relentless pressure to keep moving makes locust swarms one of the most terrifying natural forces in the animal kingdom. Every locust is both a predator and potential prey—a nightmarish existence where stopping for even a second could mean death.
4. The Devastation of a Locust Swarm
While the cannibalistic behavior of locusts is terrifying enough, their impact on agriculture is even worse.
? Locust swarms cause:
- Massive crop destruction—devouring everything in their path.
- Food shortages—affecting entire regions.
- Economic devastation—ruining farmers' livelihoods.
Some swarms are so large they can block out the sun, and their feeding frenzies can strip entire fields bare in a matter of hours.
? Fun Fact:
A single desert locust swarm can eat as much food in one day as 35,000 people!
5. Can Anything Stop a Locust Swarm?
Locust outbreaks have been recorded for thousands of years, with ancient texts describing them as biblical plagues. But even today, they remain one of the hardest pests to control.
? Methods of control include:
- Pesticides—but they often arrive too late.
- Fungal biopesticides—which infect locusts with deadly spores.
- Drones & tracking technology—to predict where swarms will form.
However, because of their ability to rapidly breed and travel long distances, locust swarms remain one of the most unstoppable natural forces on the planet.
Final Thoughts: The Horror of the Locust Swarm
We often think of insects as mindless creatures, but locusts prove that nature’s survival strategies can be shockingly brutal. The idea of millions of insects flying together, eating each other alive in mid-air, sounds like something from a horror movie—but it’s happening right now, across the world.
Next time you see a harmless grasshopper in your backyard, just remember—it might be one bad day away from becoming a ravenous, skyborne cannibal.
Would you want to witness a locust swarm in real life? Or does the thought send chills down your spine?
