Good question, massaman. It's been playing on my mind as well.So, the spermatophore is sustained in the female like male ******, huh? Does that mean a mated female is pseudo-hermaphroditic?
I have noticed fewer nymphs hatch from the later ooths but this may be due to the later ooths often being smaller and not anything to do with mating. If I have a male I see no reason not to mate the females again.
