Bayou George, FL. My yard.
This magnificent creature is harmless, even though the colors say “Stay Away”.
Its host plant is the oleander, and is also called the Oleander Moth.
In the last few years, I’ve not seen any.
They love nectaring in goldenrod and if you are fortunate, the colors are nothing but thrilling, but Bidens alba (Spanish Needles), the plant it is shown on, is a favorite as well.
