Most of the time, desert locusts live a solitary existence. But when they experience a sudden spike in serotonin, a neurotransmitter found in all animals, it's time to swarm! Scientists at the University of Oxford recently found a close connection between the levels of serotonin in
the insects' bodies and how
sociable they became.
the insects' bodies and how
sociable they became.
"Locusts switch into swarm behavior based on two cues: when they see and
smell other locusts for an extended period or when their hind legs are
constantly jostled."
Just so you know: when locusts are green (above) they are feeling mellow, when dark-colored they are ready to party.

When I search locusts, like the one pictured here, I find what people in my area have always called grasshoppers. What people in my area refer to as locusts (the ones that swarm every 7 years), seem to be cicadas. I suppose they're all closely related? I'm researching, but I'd appreciate if anyone knows the answer.
What is wrong with you, USA, why you no like new things? :(

I want my lamb and mint chips. I hate having to have friends mail them.
I replied, I'd rather just have chili and cheese, not a fake taste. No for me.
Oh and you better check the ingredients: Five Foods That Cause Anal Leakage.
