What one is the odd one out of spider fly ladybird or a beetle?

Well, isn't that just a happy little question! Each of those creatures is unique and special in its own way, just like you are! But if we had to pick, the odd one out would be the fly, because it's the only one that can fly but doesn't have a hard outer shell like the others. Remember, there are no mistakes in nature or in life, just happy little accidents!
