Extract

In the late summer of 1940, there was a decided peak in the abundance of the monarch butterfly, Danaus plexippus L. Numerous reports were received by the Royal Ontario Museum of Zoology, and a personal investigation proved the abundance of the species; trees bordering the north shore of Lake Ontario in the vicinity of Toronto were literally covered with monarch butterflies.
