Locust - (Pillagers of Crops)

With 1.15 update bees will be added.
As we recently learned, they will help you with growing crops.
So i figured out, there is a balance in all things(-some philosopher, probably).
So there should be something that can destroy your crops; Locust. "Perfectly balanced, as all things should be"

Obviusly tho, they would be very rare. Another thing that would make it more balanced would be the necessarily crop size for them to even attack. Maybe 2x size of the village farm?

There is a REALLY big benefit of adding Locust;
That is, it would either force(if farmes would be too big) or encourage people in later stages to be extra creative and build. Which is a really big(arguably biggest) part of Minecraft experience.
Either they would build farms far away(to cheat the system) or create special houses/baricades/building/walls for crops.

Add or discard any part of this, thanks for reading.
