Though we have seen dozens of caterpillars munching away in our milkweed garden, this was the first one to turn into a visible chyrsalis — we think others have discretely transformed and flown away. We didn’t know what to expect, but this bright green globe with its little gold spots was a marvel. Lately, toward the end of October, we have seen a half dozen. They seem to have taken over a telephone junction box as Caterpillar Hotel.
