The days are getting cooler now, and already the monarchs are beginning to disappear, continuing their journey toward warmer climate. A book I own tells me that monarchs, once they've arrived at their migration destination, will make "butterfly trees": they'll settle themselves by the thousands over the limbs of great evergreen trees, wait out the cold weather, and then wake to head back north. Only this time, they won't complete the journey. They'll mate, lay their eggs on milkweed plants, then die. Their eggs will hatch into caterpillars, feed on the milkweed (that's important) and become new butterflies. And because their new little bodies will be full of the milkweed on which they've fed, these little creatures will be safe from the beaks of hungry birds (which are allergic to milkweed). Protected, they will finish their parents' journey home.
Astonishing to me.
