Can you elaborate a little on what asexual reproduction actually looks like?

I clarified they're clones of their mothers, not sure what else to say.

"new species readily switch between the two."

What do you mean by that?

Otherwise, it's an excellent bloodsucking mite/aphid idea, with delightful shiny art.

Genus groups are assumed to speciate readily, and when new species evolve in this case they may switch diets with little to no transition.

So just for my understanding, they asexually reproduce with internal eggs that they then give birth to live young?

Yes.
