Corrected entry: When Gediman is rambling about the queen's new 'perfect mutation', he fails to realize how imperfect it actually is when compared to its normal state. Instead of cranking out hundreds of eggs in a short amount of time which can lead to a huge army being built in a matter of months, now the queen has to spend countless hours straining and suffering while trying to force out an awkward, bumbling monster that attacks her on sight. Hardly a situation that I would describe as 'perfect'.
Correction: He might have referred to the fact that the alien species can now reproduce without the need for hosts.
Correction: Gediman obviously does not consider the relatively low birth-rate to be important, the mutation is perfect by his personal criteria. Others may disagree with his opinion, but it is (at most) an error on the part of the character, not a movie mistake.
