I wonder. Actually, Langstroth's orig. hive had an upper vent/entrance.
He must have considered it important from the get-go. Some of the factory
inner covers have had a tiny port in the rim, but this is not very
substantial.
During winter all our outer covers are raised about 3/8" above the inner
cover rim with wooden risers (sort-of like the matchstick idea) a la Manley
and this keeps everything nice and dry -- no moldy brood combs or soggy
bees. I think it is helpful in summer, too, for the air flow.
As far as wax moths go, even if they get in through an upper entrance, say,
on a cold night, still, any colony strong enough to need the extra entrance
will be able to deal with any intruding moths. On a really weak colony it
would be a concern, though.
