Insects are so small that you can't see that, you don't know where they are looking, or if they are afraid or not.
Looking at macro photography of insects, you can see how they are build and the spiders (especially the jumping spiders) are quite cute. Knowing how they look and their behavioural patterns, and just reading more about them, allowed me to be less afraid of them.
Now I don't know if that is "scientifically correct", but it helped me.
Horses on the other hand, are a lot more nervous, but I can read them and I can 'manipulate' them. They are probably more dangerous, but they are less scary to me.

There are some repellant looking arthropods, but these moths are the beginner level in getting used to looking at such creatures.
Bug shots, bug squishing, blood in movies? Squished brain etc.? All good to most degrees.
I pass out during 2D animation demonstrations on how bodies work.
I pass out during nasal allergy tests. I can't imagine how I'll go with a covid test.... pass out most likely.
I don't get put off by blood at all. I can handle (and in fact enjoy) gore in movies, horror movies, etc. But man, I don't know what it is with insects. Their tiny spindly legs, weird beady eyes, the wings, their hair, their antennae. Can't stand looking at it.
Fascinating creatures, but boy do they mess with my mind like nothing else.
