I wrote an essay “An Opportunity for Butterflies” for https://www.ontariowoodlot.com/ at the end of the last year all about butterflies you may encounter as you move from deep forest to woodland edge to open meadow in Ontario. You can check out a preview below (or on their website):
While some species are suitably adapted for living off of the resources available in the forest, woodlands lack the nectaring resources the majority of butterflies need. Many species lay eggs on woodland trees that will then require flowers as adults. Where the woods break into open spaces, you will more commonly find these species. Thanks to the Ontario Woodlot Association for giving me the opportunity to write for their members!
