MaryAnn Lepp in La Broquerie, located about 60 kilometers southeast of Winnipeg, observed a significant increase in monarch butterflies in her garden this summer. She counted 20 caterpillars feeding on her swamp milkweed in just one day. This surge in monarch activity is being witnessed by numerous Canadian enthusiasts across the Prairie region, where backyard milkweed patches are thriving due to the wet and hot weather conditions.
Although the exact reason for this increase is not confirmed, experts are noting the positive impact on the federally endangered monarch species. Reports of caterpillars, chrysalises, and butterflies are being shared enthusiastically on social media platforms like the Manitoba Monarch Mission group.
Marika Olynyk, curator of the Living Prairie Museum in Winnipeg, mentioned the abundance of monarchs this year and the continuous presence of caterpillars and butterflies throughout the summer. Despite efforts by many individuals like Lepp to plant milkweed and native wildflowers, habitat loss remains a significant threat to monarchs due to the conversion of native grasslands into farmland.
The monarch’s legal status was upgraded to endangered in 2016, and regulations were implemented in December 2023 to protect them on federal lands. Conservation efforts are ongoing, with organizations like the Assiniboine Park Zoo working to breed and release critically endangered butterflies like the Poweshiek skipperling.
Laura Burns, the conservation programs manager at the zoo, expressed optimism about the recent sightings of Poweshiek skipperlings, indicating progress in their conservation efforts. Weather conditions this year have also been favorable for various butterfly species, including monarchs and Poweshiek skipperlings.
As part of a Canadian Wildlife Service project, zoo staff will be tracking monarchs’ migration to Mexico by attaching radio transmitters to them. Enthusiasts like Lepp are dedicated to fostering a healthy environment for monarchs to thrive and contribute to biodiversity conservation efforts.
The community’s involvement in protecting these butterflies highlights the importance of coexisting with nature and preserving ecosystems for future generations.
