I was there last Monday (2/12/18)and the butterflies where still there.
I've found that the people at the visitor center, which you can call by phone, can give a very accurate update based on that day.
During the Spring season. Not as much, but they are still there
Some, not all. They are staring to migrate. They are usually there till March.
I saw none when i was there in January and was told it wasn't the season for them.
It was too cold when I was there...Not moving around, but we did see a few
No, flew away
