Krovus' quest doesn't give a journal entry, and is only available to very low-level chars. It seems a tad bugged, but this isn't about that.

Might I suggest adding a small QA with beetles for Krovus where one might go - and perhaps some reward (beetle meats with different properties or half-digested gear?) for doing it and there gather some meat by killing beetles - really, just making it into a regular quest?

There's a place where you can harvest this already. I'm sure you know where it is! It's just a matter of taking it from point A to C instead of point B! >.>

Sorry, that was kinda of cryptic.

While of course there might be somewhere it may be harvested allready, I still personally think that it would be better to add an own QA for the quest, and make it a more "proper" quest than just a less paying variant of the "hunt Rothe" quests.

There is a QA. However, it is not next to Krovus.
