If larvae are stressed to the point of death prior to metamorphism doesn't that mean they aren't surviving long enough to pass on their genes? So wouldn't that characteristic eventually fade out based on the principles of natural selection? And wouldn't the ones that don't stress out to the point of death, or lack of development, be the ones that survive to breeding age and spread the genes that don't exhibit theses behaviors. Rather wouldn't they spread the genes that allowed them to avoid that fate in order for the species to survive. Wouldn't the genes that code for stressful dying eventually become less prevalent within the population?
