A new theory into the mystery of why Monarch butterflies are vanishing. For several years, scientists have theorized the loss of Milkweed plants, which Monarch larvae and caterpillars feed on, have been a major factor in the dwindling population that migrates up to 3,000 miles from Canada and the Northeastern U.S. to mountain forests in Central Mexico.
We’ll hear from a Cornell University researcher who believes the greatest threats facing the butterflies lie somewhere during the final leg of their amazing yearly migration, through Texas and Mexico, and beyond the stages where the Monarchs rely on sufficient amounts of Milkweed.
