I just think calling any of that "Lethal" is irresponsible. People seem to hear that and start spreading the crap that if you breed spider x spider the babies will die, or some variation there of, when we really do not know whats going on. Lethal is a bad and likely incorrect term. Has anyone proven that circa 25% of the time eggs die? I dont think anyone has proven anything, because not only enough pairings, but whose keeping track? Maybe im wrong? But I dont think anyone is going to do the necessary breeding.
