"The Second Brood" refers to a phenomenon in which certain species, particularly insects like cicadas, produce a second generation within the same breeding season. This occurs when environmental conditions are favorable, allowing for a rapid life cycle. The second brood typically emerges after the first, contributing to the population's overall growth. In the case of cicadas, the second brood can lead to overlapping generations, where both the first and second broods are present simultaneously. This strategy helps ensure the survival of the species by increasing reproductive opportunities and enhancing genetic diversity within the population.
