‘Tis the season for monarchs in the Arb

Last Thursday, MPR aired a story titled Minnesota monarch butterfly population falls.

Minnesota’s monarch butterfly population is 38 percent below average this summer, according to preliminary statistics from University of Minnesota’s Monarch Lab. Cool, dry weather is likely the prime culprit, but ecologists also suspect human beings are playing a role.

    A friend of mine who lives in Tulsa, Oklahoma and is an English woman, and avid gardener, agreed with an observation I had made earlier this summer about the larger size and different markings we had seen on the monarch butterflies of both Southern and Jamaican species.
    I wonder if it’s evolution or more nutritious milkweed or ???
