Come join us Wednesday morning from 10am to 11am at the Sawyer Free Library where I will be sharing Monarch fun with young people. We have art activities, as well as eggs, caterpillars, chrysalides, and possibly a butterfly or two emerging on the day of the program. I hope you can join us!
2019 has been an amazing year for Monarchs. We got off to a very early and fantastic start, but then with a wave of cool rainy weather the Monarch movement slowed considerably. Despite the slow down, we’ve had at least two subsequent waves come through for a total of three broods this summer. Hopefully this will translate to a great 2019 migration followed by strong numbers at the Monarch butterfly’s winter sanctuaries at Michoacán and the state of Mexico.
The eggs we see now on milkweed plants are the super generation of Monarchs that will travel to Mexico.
The photos show the Monarch caterpillar becoming a chrysalis. When ready to pupate, the caterpillar finds a safe place and spins a silky mat. He inserts his last pair of legs into the silky mat and hangs upside down in a J-shape for about a day. Biological developments that began when the caterpillar first emerged are in high gear now. The caterpillar’s suit, or exoskeleton, splits along the center line of the thorax and shrivels as the developing green chrysalis is revealed. The last photo in the gallery shows the moment when the old skin is tossed off.
