True or False: Not all termite colonies swarm annually.

The statement that not all termite colonies swarm annually is indeed true. Swarming behavior in termites is influenced by various factors, including the type of species, environmental conditions, and the health of the colony. Some species may have specific swarming cycles, and environmental factors such as temperature and humidity can also affect whether or not a colony swarms in a given year.

In particular, colonies may choose to swarm during optimal conditions to maximize their chances of survival and reproduction. If conditions are not favorable—such as during prolonged droughts or excessively cold temperatures—some colonies may skip swarming for a year. Additionally, some species naturally have irregular swarming patterns, making it evident that annual swarming is not a universal trait across all termite colonies.

Thus, the correct choice highlights the variability in swarming behavior among termites, reflecting the complexity of their reproductive strategies in response to environmental cues and species-specific behaviors.
