We know there are known issues with line breeding certain mantids, the problem is without a real scientific study we dont know if its due to the line breeding or husbandry and this weve seen in the dart frog hobby as well. Id be more than happy to start holding back a few Hymenopus to start studying this. A few simple set husbandy/ feeding practices and a controled breeding setup with tracked individuals will tell us something.
As far as FF go, you need to understand that FF are already so inbred to the point they are deformed, Why do you think there are so many strains of them, wingless, golden wingless, turkish gliders, curly wings, and such you dont think they are all naturally occuring do you?
They also do not start producing runts do to breeding, its lack of food, they will keep breeding even without food in the bottom of the culture, the FF do not eat the media in the bottom of the cups for the most part, thats for the larva the FF go after the yeast in it and you will see if you sprinkle a bit of yeast in there a couple weeks into production they will flurish longer. Its also a genetic issue with how most seed their cultures, you should be seeding each culture from 3 seperate cultures, one from fresh producers, one from mid stage and then from the late stage in the culture, this creates a a stronger FF population in your culture.
