i cant quite imagn a scrab having sex cause they just shread any animal that comes to close (well within there teritorial bounds) and i think they would shred a female (possibal future mate or not)
i think that they could be asexual or possibly when they die they release something that creates a spore which a new scrab comes from (dont ask me why but i really what at least one creature to be able to have been made by a tree or plant)
