Monarchs on the move...so many mysteries. Where do Western monarchs go after leaving their overwintering sites along coastal California in February? An observation: They didn't stop in the spring or summer to deposit eggs on any of our four species of milkweed in our Vacaville pollinator garden. Spring? Zero. Zilch. Nada. Summer? Zero. Zilch. Nada. Fall? Yes. Why not spring and summer? Did the monarchs passing through Vacaville opt for "a better habitat" in the cooler Pacific Northwest...
