I just got done with the wax moth section in Langstroth's Hive and the Honeybee. He calls it the Bee Moth. He talks about the wax moth like modern beekeepers talk about SHB. Sometimes, he makes the problem sound nearly as serious as Varroa is today. Even to the extent of apiaries being decimated by it.

So, here's my question: Have bees evolved since Langstroth's time to be better defenders against wax moths? Or am I just in an area where they are not a problem? Judging by this forum, wax moths seem to be a minor annoyance rather than the full blown crisis Langstroth talks about. I read much more on here about SHB than moths.

Thoughts?
