And after that?

Bee's and wasps or hornets
Bee's are neutral but get extremely aggressive once the player destroys the hive to get honeycomb (either to heal or for side quest).
wasps are a tiny bit bigger than Bee's but instead are aggressive and will attack on sight and use a mild aphrodisiac on there stinger.
Hornets are as big as the rats (in this game) and will follow you until you get inside a building or integrate with it.
I think that's a good idea.
