If I could be any insect, I would probably want to be a grasshopper because they seem like very simple and mellow insects.  They can also jump really high and aren't really that small.   Another reason why I would be a grasshopper is because most humans leave grasshoppers alone when they see them.  They don't usually step on them like a beetle or spider.  This is mainly because grasshoppers are larger and not so creepy looking.  They generally are given a break when it comes to being stepped on or run over with a bike.  They are also easier to see on concrete, but not neccessarily in the grass.  Since they are green they blend in more with the grass.
