The werewolf of the insect world, locusts are a species of grasshoppers that transform into ravenous, flying beasts under certain conditions.
Your prompt is LOCUSTS.
Insatiable swarm
When overstimulated
They gorge without thought
During periods of overcrowding, increased stimulation of grasshoppers’ legs triggers a release of serotonin. This, in turn, causes the grasshoppers to change appearance, eat more, swarm, and breed more readily.
The first little bite
Itches, the second scratches.
The millionth cracks bone.
Air reverberates
Our fiddle strings played red hot
Melody a plague
