What structure do termites have that differentiates them from ants?

Termites are distinctly characterized by having wings that are roughly the same size when they are in their reproductive stage, specifically during swarming season. This feature sets them apart from ants, which typically exhibit a clear size difference between their forewings and hindwings; the forewings are generally larger.

In addition to wing size, termites have other notable biological features. For instance, their antennae are straight rather than elbowed, which is a trait that ants possess. The body structure of termites is also more uniform and less constricted compared to the segmented body of ants, which can appear very pronounced with a narrow waist. Lastly, the surface of termite bodies is usually smoother, contrasting with the hairy bodies of many ant species. Understanding these distinctions is crucial for accurate identification and pest management strategies.
