I don't have a problem with most bugs, but I particularly hate ants, flies, and bees because they're just really annoying (my school is infested with bees, for some reason, and everyone freaks if one even flies into a classroom. That's actually what makes it more annoying than it is. Just ignore it, people!).
As for ones I like, I'd say dragonflies. Dragonflies are quite pretty and I rarely see them so it's always cool to run into one. I like caterpillars and ladybugs as well, they're cute.
