The firefly optimization technique gives the reduced order model for the higher-order interval system. Stimulated by sporadic behavior of fireflies to act as the signal system to impress other fireflies. The fitness function is developed using   Routh approximation and cross multiplication of transfer function. The stability is analyzed through Routh-Hurwitz stability.
