MaryAnn Lepp witnessed a significant increase in monarch butterflies undergoing metamorphosis in her garden, observing 20 caterpillars feeding on her swamp milkweed in a single day this week. This surge in backyard milkweed patches across parts of the Prairie is being celebrated by numerous Canadian monarch enthusiasts, including Lepp in La Broquerie, located about 60 kilometers southeast of Winnipeg.
The surge in monarch activity, including sightings of caterpillars, chrysalises, and butterflies, has sparked excitement among butterfly enthusiasts, who are sharing their observations on social media platforms like the Manitoba Monarch Mission. While conservation experts cannot definitively attribute this increase to favorable weather conditions, the growing number of monarch sightings is considered a positive sign for the federally endangered species.
Marika Olynyk, the curator of the Living Prairie Museum in Winnipeg, noted a substantial presence of monarchs this year, with a consistent population of caterpillars, chrysalises, and butterflies throughout the summer. The museum’s tall grass prairie preserve boasts a variety of native plants that attract pollinators, including different milkweed species favored by monarch butterflies.
Despite efforts by individuals like Lepp to plant milkweed and native wildflowers, these habitats remain scarce due to historical land conversions for agriculture. Habitat loss poses a significant threat to monarch populations, emphasizing the importance of conservation efforts to protect these iconic butterflies.
In response to the declining monarch population, the Canadian government upgraded the legal status of monarchs from “special concern” to “endangered” in 2016. Efforts to support monarch conservation include tracking their migration to Mexico, where researchers estimate the population by measuring the acreage covered by monarchs in wintering grounds.
While monarch numbers have seen a boost, Laura Burns, the conservation programs manager at Assiniboine Park Zoo, highlighted the precarious situation of the Poweshiek skipperling, an even more critically endangered butterfly. The zoo’s breeding and release programs aim to bolster the Poweshiek skipperling population, offering hope for its recovery amid ongoing threats of extinction.
As monarch enthusiasts continue their efforts to protect these butterflies, initiatives like placing radio transmitters on adults to track their migration further demonstrate the commitment to preserving these species and their habitats. The collective actions of individuals like Lepp underscore the importance of fostering a harmonious relationship with nature to safeguard biodiversity and the environment.
