aswarm
Full of many
Aswarm means teeming or crowded with moving things, as if covered with a swarm: The beach was aswarm with tourists.
The word nearly always appears after a linking verb like "be" or "become" and takes "with" to specify what's swarming.
It carries a sense of restless, slightly overwhelming abundance.
