It's not a mistake. To evolve them they have to be traded together. #616 (Shell with red bug) basically gives his shell to #588 (yellow & blue bug) so he can evolve to #589 (knight bug).
If you look closely at the knight, it's pretty obvious that it's the yellow & blue bug in there and not an accidental mixup.
