I personally like ants alot.(I'm sure you can tell.) They're strong,smart,fast,abundant,some are bigger than your thumb,some have bites as painful as a bullet,and the way they have colonies with millions of induviduals is fascinating to me.
I don't like any kind of insect. I especially hate when they craw on me. It gives me goosebumps. I also hate when flying bugs like flies fly close to your ear and make that buzzing noise.
I think dragonflys are strange because they only live for 24 hours. But i would have to say a giant fighting beetle. There so huge for bugs. I saw one in a youtube vid once it was very cool.
