When the title says "UU Team" I think the common inference people are going to make is that it's for the UU Metagame.
Also, your pokemon hardly work together. If you want to BEAT OU teams that are well constructed and in the hands of a good player, your team will have to be good enough to give yourself a chance to win...but your team is weak to almost every single OU sweeper, except what Blastoise walls. you can't really expect to beat OU teams using Butterfree.
Before sims kills me for this line, I'll just say that it is okay if it works within the team, but it clearly doesn't which means that its weaknesses will be preyed on much more easily.
With that in mind, replace the dead weight (Lanturn...Butterfree...) and add in pokemon that give you much-needed resistances. Get a rock resist for sure, and a better fighting resist than Butterfree. Claydol is probably your best bet.
