Common milkweed gardens increase occupancy by monarch butterflies and other specialist herbivores towards an urban centre

open access: yesInsect Conservation and Diversity, EarlyView.
We surveyed 119 stands of common milkweed (Asclepias syriaca) across an urbanisation gradient to investigate how restored garden habitat might ameliorate the negative effects of urbanisation on specialist herbivores. Surprisingly, we found most herbivores (including the monarch butterfly) had greater occupancy on common milkweed towards an urban centre.
