@365projectorgjoworboys Hi Jo! Yes, I think of them as little stained glass windows! (but big butterflies!) They have been classified as endangered, so it's always a thrill for me when I spot one :-)
Another lovely one. You may have had to wait a bit to get the first but by now you have a lovely selection of beautiful monarchs. From what I can tell I think this one is a male.
@gardencat Thank you, Joanne. I just googled male vs. female monarchs. And yes, I think you're right: two black spots on the veins of the hind wings. Thank you for leading me to this new info! :-)
