Three years ago, I planted pink milkweed, Asclepias Incarnata, in the back of our house to attract and help Monarch butterflies, whose number has been in decline in recent years. The first year several came, and then there were Monarch caterpillars crawling on the milkweed plants. Then after a few days they disappeared, maybe eaten by the many birds flying around our bird feeder. Last year, not one single Monarch showed up.
This year, at least one did appear, captured in the following photos.
