Where Are the Monarchs?

Wednesday, December 04, 2013

This year, the annual migration of monarch butterflies was just 3 million, down from 60 million the year before. New York Times contributor Jim Robbins talks about why some experts are worried that the migratory pattern could be on the brink of collapse. His article, “The Year the Monarch Didn’t Appear,” was in the Sunday Review on November 24.

These creatures like all insects are valuable in and of themselves. They don't need to have human usefulness to appreciate the catastrophe that is happening around them.

Correction: Although the Monarchs who migrate north in the spring do come in successive generations, the Monarchs that migrate south to Mexico in the fall DO make the journey in one generation . This can be a 3000 + journey for many.

One thing everyone with a yard can do to encourage our glorious monarchs is to plant milkweed (asclepias) flowers in their garden. You can get them at any good garden center and they're not only beautiful, but provide both habitat and food for monarchs, who will reproduce on nothing else! This is much more valuable to monarchs, and thus, to the ecosystem, than alien plants that only produce nectar, such as the widespread (and invasive) "butterfly bush" (buddleja).
