One of North America's largest and most beautiful butterflies might be on the ropes. The monarch butterfly Danaus plexippus* has two big challenges: it migrates halfway across the continent, and it relies on an agricultural pest plant to survive. Deforestation of its southern wintering spot and industrial control of its host plant are converging to make life tough for an insect recognized as state insect or state butterfly for seven US states.
This individual and several like it that I saw in the Missouri Botanical Garden was among the very few I've seen this year. Citizen science is catching up with anecdotal evidence to prove that the population of monarch butterflies is plummeting. We should all plant milkweed in our yards, and hope that the orange giant is with us for years to come.
