Butterflies still showing up on mystery tour island?

[AlyssaAC]

OK, so I just went on a mystery tour and this was before 7pm. After 7pm hit there was still butterflies popping up?... Do they only disappear if you go to the mystery tour island after 7pm?

Note: I'm also talking about tiger butterflies and blue bottle butterflies, which I could of swore they were gone after 7pm...

Next time, you could try catching all the butterflies and see if new butterflies would spawn.

It's because you showed up before 7 and let the clock turn while there. You have to wait until 7p to fly out to ensure no unwanted bugs spawn.
