I am getting ready to order my first hive components, going with 8 frame boxes. I have looked all over and have been unable to find out the difference between hive boxes and super boxes. Are they the same, defined by where they are in the hive? At one point I thought the hive box had an opening, but it looks like the entrance to the hive is actually in the base. The Mann Lake catalogue does not appear to have a separate listing for each.
