Monarch migration dips to lowest level in two decades

In spent the better part of a fall day a decade or so ago watching migrating Monarchs fly over the mouth of the Chesapeake Bay on their way south to wintering grounds in Mexico. And my field trip log books are filled with notations of other memorable Monarch sightings, like those found near my previous home in Pennsylvania on the late date of Nov. 10. This NY Times article is filled with dreadful news of the species' diminishing population on wintering grounds in Mexico.The indiscriminate, criminal spraying of milkweed-killing herbicides on the margins of rural roads in Pennsylvania and across the Northeast for that matter is deadly.
