Hello, thank you for your work. I live in Northern California by Santa Rosa. At my house and in the garden at work I have seen a monarch butterfly with the swallowtail. I can’t find anything on the internet about it. I have seen them for weeks at a time. The markings and size are that of the monarch but definite little tail. Do you know about this? Thank you, judy Leave a Reply. |
