This when the reproductive termites leave the colony to start new colonies. Ants also swarm in the spring time and often swarming termites are mistaken for ants. There are some obvious differences though.
Ants have a body shape with the narrow waist, which actually between the thorax and the abdomen of body, giving the wasp shaped body. Termites have a tapered body.
Termites also have four oval wings equal in size. Ants have four wings that are different size and not oval but appear cut on one side.
With this knowledge you can easily distinguish between termite and any swarmers."
