The picture below is a bit fuzzy, but it will give you an idea of how many butterflies were clustered on one branch.....they were like this on several branches of the trees. It looked to be hundreds of them.
I did some research online and found a site where you can report sightings of the butterflies as they make their journey south to Mexico. I am going to do this! :O)
I'm so glad that my guest spotted the butterflies while bird watching today, otherwise, I would have just walked right on by, missing a truly amazing sight!! :O)
