Yeah - but why complicate stuff. Its not like the rest of Ark is uber realistic.
We dont need larvae for the moth. We dont want the female mantis to kill the male.
The moth,mantis,scorp already drop eggs, so adding fertilized eggs shouldnd be an issue.
The bat is a mammal anyway, so easy.
The only creatures that might be a lot of work is the dungbeatle, arthro.
But hey, we have a fish that mines metal and another shoulder pet. We should be happy, right.
Im so salty/dissapointed.
