funnily enough, there actually is a species of locust that used to swarm over a large part of the US, but which a bit over a century or so went extinct.
the wiki article on the species Im thinking of (rocky mountain locust) suggests that one possible explanation for their extinction is their eggs being destroyed when people started plowing and farming the area they would breed in, so It might line up due to having the same general cause.

Doesn’t that line up roughly with the dust bowls?

Cicadas still exist.
