Personal memory by Rob Wald
1968 • Lafayette, California, USA
I remember an empty lot I would walk past on the way to and from my school bus stop. In the spring, there would be many thousands of monarch caterpillars in that lot, munching away. Sometimes, they would try to cross the road, and cars would squash them. There were so many caterpillars that by the end of spring, the road would be plastered, but many many more caterpillars survived and metamorphosed into beautiful butterflies. That monarch habitat was destroyed decades ago when houses were built on the lot.
