My name is Matthew. My family and I were on vacation up near Bear Lake, on the boarder of Utah in Idaho. Up in Paris, Idaho we saw a bunch of orange and black butterflies. I can send you the original files as well. The music on the clips came from YouTube audio library and require no attribution (I doubt you'd need to edit in the audio anyway). These were slow motion shots I got from my iPhone. One woman we talked to thought it was a butterfly migration, but I talked to my grandpa (Dr. David Havertz) who has a Ph.D. in Zoology and studied insects for his career. He thought that the butterflies had recently come out of their cocoons and were feeding on something. I'd be happy to get his official opinion in writing, if that's helpful. You don't need to pay me anything. You don't even really need to give me credit, although you can if you want to; I have videos on my YouTube channel about Bear Lake, which is right near where this clip was shot. It really is a great place to visit.
