Laying females will dig a brooding chamber, lay the eggs and then wrap themselves around their brood. They will wait until they hatch (as these have), then continue to guard them for their early life. The mother will spend months curled up like this and won't eat for all that time. These young centipedes are near the very end of that period and will soon be fully independent.
As much as I like centipedes, they're basically the only animal I can't bring myself to find cute. Really viscerally disgusting. And yet for some reason millipedes are just adorable.
