Welcome Monarchs

Until yesterday, and since March, I've seen zero monarch (Danaus plexippus) caterpillars in the garden.
It's cold enough to wear a wooly beany during the day; chilly enough to make me to remember the long hot days of summer fondly; and wonder why there were no caterpillars during summer's bounty of succulent leaves and flowers.

But now that the milkweed is cold-purpled and thin, I find these two little guys munching away.

This one is sandwiched between two leaves . . . cozy?
