What type of termites swarm at dusk in large numbers?

Formosan termites are known for their unique swarming behavior, which typically occurs at dusk and in large numbers. This behavior is significant as it differentiates them from other types of termites. Formosan termites are a highly aggressive species and are notorious for their rapid colony growth and ability to cause extensive damage to wooden structures. Their swarming behavior helps in the dispersion and establishment of new colonies, which is crucial for their survival and spread.

In contrast, other species mentioned do not have the same swarming behavior at dusk or do not swarm in such significant numbers, making Formosan termites particularly noteworthy for this characteristic. Understanding these behaviors is vital for effective pest control and prevention strategies in environments susceptible to termite infestations.
