The King is (Almost) Dead?

The orange and black Monarch butterfly (Danaus plexippus) annually undertakes the longest insect migration. Monarchs over-winter in Central Mexico but, in Spring, progressively move North, as far as Southern Canada (https://abcnews.go.com/Technology/wireStory/beloved-monarch-butterflies-now-listed-endangered-87176460). Millions of butterflies make these impressive moves and people travel considerable distances to see them. Over the last 10 years, however, Monarch butterfly numbers have declined between 22 and 72% (depending on how it is measured). This decline may be linked to habitat destruction (the larvae feed on Milkweed); insecticide use and climate change. The Monarch's population crash has resulted in its being placed on the International Union for the Conservation of Nature's 'red' (endangered) list. This sad fact is another warning that an insectageddon is currently underway.
