Learning about Monarchs Butterflies and Caterpillars

We have been studying Monarch Butterflies in class and are learning a lot about them. Here are some facts from the students in our classroom... When they are caterpillars they are white, black, and yellow. Whenever the larva hatches it eats its egg. To make itself poisonous it eats milkweed. It flies to Mexico or California in the winter. They lay their eggs on milkweed. The Monarch caterpillars shed their skin 5 timers. Their poop is called frass.
