In the coming month WATCH FOR “super generation” monarch caterpillars (which will fly all the way home to Mexico this year) on milkweeds! Listen on these hot nights for cicadas, tree crickets, and toads. Consider joining the Green Acton Biodiversity Committee to learn how to control rodent pests safely without resorting to rodenticides which kill precious wildlife.

Rob Gogan is a West Acton resident and compiles the Acton Nature Watch feature. He is one of the organizers of Green Acton’s Biodiversity Committee.
