After I caught my Scarlet millipedes mating, I separated the female and found a handful of eggs to monitor.
This is the pupoid stage, where antennal buds and limb buds are visible, as well as indentions for the mouth and anus.
Protonymph must be the same. It looks the same; like a little croissant. It is a legless stage after the egg and before they get legs. Somehow they move! I have seen them on the surface and then I will see them buried. Unless the adults move around them to help bury them?
Yes, I have a few growing babies isolated in a small plastic dish between two moist cotton rounds so I can check on them every day and they won't go anywhere
Hopefully more pics to come as they get bigger
