Behavioral ecologist Stephen Simpson has proposed the cannibalistic forced march hypothesis[36], that is, the forward motion of a locust swarm is essentially sustained by each individual’s imperative to avoid being eaten by the locust behind it: 1) Align their body axis with neighbors (parallel) to minimize the chances of a side-on attack and present their narrowest possible profile to the individual behind. 2) March forward to bite and feed on the abdomen of the locust immediately ahead.
A billion crazed insects marching through eating all your crops while cannibalizing each other does seem relatively twisted and demonic.
One small detail I remember was when the sun was just behind a building, you could see this glow around the building which was the sun reflecting off all the locusts that were flying around it
They were ravenous things. That ate everything. Not just "food," either, though eating a snack outside was certainly impossible and merely being outside was treacherous.
These bugs ate things like window screens, cut slivers from a vinyl swimming pool, and dined upon the siding of the house. It was really fuckin' weird even being inside of the house, since the noise of it being pelted by grasshoppers (locusts?) never really slowed down.
That was probably 25 years ago. It never happened again.
