Hi Orin, Thanks. I actually have a freshly eclosed virgin female. She emerged day before yesterday, that last male yesterday. I guess it was just a lucky pairing that bought out that trait. This is the 4th gen., and never a hint of red. And I only kept a dozen grubs! Kind of strange these males were the last to eclose and also by far the smallest. I'm pretty stoked!
Do you think that each mating fertilizes new eggs or are they all fertilized together?
Going to be alot of work trying to raise that many grubs. Take care.
