A swarm is a group of many small animals that fly or move together. You might see a swarm of birds flying around a bird feeder.
When we talk about swarms, we often think of insects like bees, wasps, or mosquitoes that gather in big groups. Imagine walking through a park and suddenly seeing thousands of tiny creatures buzzing around you - that's what it means to be surrounded by a swarm! People might also talk about a swarm of people, like at a concert or festival where everyone is together having fun. In some cases, a swarm can even refer to a group of fish moving quickly through the water, creating a big splash.
A large number of insects, especially when in motion or (for bees) migrating to a new colony.
To move as a swarm.
