============
Desert Grasshoppers are mostly living alone, each leading its own way of life.

As the desert environment dries up, and leaves smaller areas of greens, Grasshoppers look for food and slowly start moving from their place. 

This eventually brings all Grasshoppers closer together.
They see and smell one another and touch and rub one another’s hind legs. 
This mechanical tickling affects a couple of nerves in the body.

Within few hours of crowding, a boost of neurochemical called Serotonin in the nervous system creates sudden  behavioral changes such as rapid movements, crowding, increased appetite. 

Serotonin not only creates behavioral change but also physical appearance.
Body Color changes from a green or brown to a vivid yellow and black.
Their body sizes getting smaller with newly developed strong muscle.

Brain grows larger. 
The wings become longer and stronger for long travel to search food.
Legs and horns shrink shorter. 

Finally harmless little green grasshoppers turn into a morphed Grasshoppers called LOCUST! 

When the group's density increased, the bugs fell into an orderly line and began to follow the same direction. 
This group formation called Swarm.

In this stage, desert locust having 3 times more Serotonin in their system.

Serotonin exist in all animals. 
Serotonin plays an important role to boost moods in humans.
It is a happy harmone. It controls mood, memory, sleep, cognition.
If Seratonin level low, then it creates depression.

Scientist did some experiment with Grasshoppers using Serotonin. 
They injected a little Serotonin into the locusts. 

It induces swarming behavior even without that hind legs physical stimulation.  
Further scientist started adding some chemicals that block the production of serotonin. 
Then the crowding behavior was significantly less.

So, serotonin is the nature's way of giving energy and swarming behavior to Grasshoppers to become Locusts.

There are thousands of grasshopper species, but only 22 can be morph to locusts. 
Desert locust is the one.

All Locusts are Grasshoppers but not all Grasshoppers are locusts.

Climate change will likely make conditions even more favorable for swarms.

The western side of the Indian Ocean was unusually warm as compared to the eastern side. 
So lot of evaporation happening over there, which turned into a rainfall in East Africa, Yemen and India,  some of the heaviest in two decades.

When the waters receded, there was a surge in lush greenery. 
This creats favorable environment for Grasshoppers. 
Dormant locust eggs start hatching, some eggs that were laid years ago. 
Then the grasshoppers grow, ate, gathered, mated, and laid eggs. 
Gradually populations of grasshoppers explode!

Locusts are prodigious fliers. 
Depending upon the wind speed, they can travel up to 150 kilometers in a day.

They can stay in their air for long periods of time. 
For Example, Locusts regularly cross the Red Sea, a distance of 300 kilometers. 
As well, Travelled from West Africa to the Caribbean, a distance of 5000 km in about 10 days in 1988.

So these unusual winds, cyclones, extreme weather is helping these pests breed fast and migrate.

Experts believe the massive locust attack because of climate change.

Locusts have entered India after traveling from Africa through Yemen, Iran and Pakistan.
Usually, locusts arrive in India during the monsoon months, between July and October. 
However, this year, the first reported sighting dates as early as April 11.

Reason behind increased breeding of locusts this year due to the Indian Ocean temperature changes,  increased numbers on abnormal rains and cyclones. 
So, increasing the number of insects over the Arabian desert roughly 8,000 fold. 
This year’s attack has been the worst in three decades. 

Scientists predict that the disaster will enhance as we enter monsoon season. 
So, Another swarm of locusts arriving in India by July.

Grasshoppers live long before Dynosours about 300 Million years ago. 
Not new to the world. Historically, the Desert Locust has always been a major threat to human well-beings.

Locusts do not cause direct harm to humans, such as by transmitting diseases or stinging.
