Swarm: Definition and Meanings

A collection of insects, especially bees, led by a queen, that leaves the original hive to establish a new colony.
Any densely packed group of creatures or things moving collectively.

Insects group: A swarm typically involves social insects such as bees that travel in a coordinated mass. This behavior happens when a segment of the hive departs to form a new community elsewhere.
General usage: By extension, the word applies to any large, moving crowd or cluster, not only insects.

“A group of social insects, especially bees led by a queen, that has left the parent hive in order to start a new colony.”

The term "swarm" signifies a cohesive, dynamic gathering, often emphasizing movement and collective purpose.
