I had fire millipedes before and they mated many times but I never found either eggs or babies. They are the most beautiful millipedes I've seen (though I've never seen Puerto rican white millies). Unfortunately they are already dead, and no offspring. Didn't you buy them at a site that ships to Europe? They aren't offered here nowadays. I want some! My ones ate rotten wood, moss, cucumber. I don't know why there were no babies as my AGBs and E. pulchires breed well.
