Insects didn't evolve into weak creatures. Scary looking little bastards, that lot.
When I was a wee kid, I captured some fireflies and put them in a jar. I put the jar on the little table next to my bed and while comfortably under the covers, I watched them flashing away. I fell asleep with a smile on my face.
The next morning, I peeked at the jar and noticed one firefly literally eating the head off of another one. I was utterly horrified, and have had a somewhat irrational fear of insects ever since.
