I have had a blast this year observing Monarchs, which I have seen daily for over 2 months. Have observed all stages except chrysalis. Other day I literally watched one hatch. I was elated.
So sad though that so many disappear over night - 8 cats on Tuesday and today only one. Couple weeks ago, 3 cats likely 3 or 4 instar on a milkweed at 8 PM and gone the next morning.
