"This year there are more Eastern Tiger Swallowtails in my garden than I have ever seen before. In years past I’ve seen one, maybe two, Tiger Swallowtails per day in my garden. This year I’m seeing 10, 15, and even 20 at a time in my wildlife garden.

And in every wildlife garden I visit it’s the same there, too. People up and down the East Coast are remarking on this phenomenon, too. And people are submitting this question through the Ask Carole feature here."
