Thank you all for your help - even though this doesn't sound all too pleasing for me

Maybe I should have been more specific; not every insect bothers me the same.
Spiders / Scorpions don't bother me at all. They're technically not even insects and suprisingly, my phobia knows the difference.
I also don't care about the small swarms of insects (they just look like tiny flying dots; even to me^^) and weirdly, beetles don't affect me either (such as ladybugs or sth).

Mosquitos or similar flies usually just make me uncomfortable but zooming out is definitely enough to stay calm. (same goes for insect-like fantasy mobs that only have some distinct features)
Ants, worms or butterflies only trigger some kind of reaction when they're really big and detailed. However, I'm usually not too bothered by them.

By far my biggest problems are bees, wasps or hornets. Zooming out is not enough in their case as they can easily trigger a full on panic attack for me :/. Yesterday, for example, I met "Giant Gnats" in Northern Shroud (I think?) and I couldn't deal with them. My friend had to do the story quest for me. Isn't it an option to let him do mandatory quests like that for me even for later contents?

Perhaps knowing about these distinctions helps to better pinpoint what dungeons or regions I should bypass (a giant bee hive as Frizze mentioned would be my personal nightmare for instance).

Thanks again for all of your help!
