MaryAnn Lepp noticed a significant increase in monarch butterflies undergoing metamorphosis in her garden, with 20 caterpillars feeding on her swamp milkweed in just one day this week. This surge in butterfly activity has been observed by many Canadian monarch enthusiasts, who are witnessing a rise in backyard milkweed patches thriving due to favorable wet and hot conditions in parts of the Prairie this summer.
The surge in caterpillars, chrysalises, and monarch butterflies has been well-documented on social media platforms like the Manitoba Monarch Mission, although experts cannot definitively attribute this increase solely to the weather. Nevertheless, the abundance of these iconic butterflies, known for their annual migration from Canada to Mexico, bodes well for the federally endangered species.
Marika Olynyk, curator of the Living Prairie Museum in Winnipeg, noted a high presence of monarchs throughout the summer, with consistent sightings of caterpillars, chrysalises, and butterflies. While monarch butterflies primarily feed on nectar from milkweed flowers, they also rely on various other flowering plants for sustenance.
Despite efforts by individuals like Lepp to plant milkweed and native wildflowers, these plants are still not as abundant as they once were due to habitat loss from grassland conversion to farmland. This loss of habitat poses a significant threat to monarch butterflies, which serve as a poignant symbol of species and habitat decline.
In recent years, there have been calls to elevate the legal protection status of monarchs from “special concern” to “endangered,” with the species officially listed as endangered in 2016. Efforts to conserve monarch populations extend beyond Canada, with researchers monitoring wintering grounds in Mexico to estimate the remaining monarch population.
In addition to monarch butterflies, conservationists are also focused on the precarious situation of the Poweshiek skipperling, a critically endangered butterfly facing extinction. The Assiniboine Park Zoo in Manitoba is actively involved in breeding and releasing Poweshiek skipperlings to bolster their population and prevent their extinction.
The zoo has reported a positive trend in Poweshiek sightings this summer, indicating potential progress in the species’ recovery. These conservation efforts, combined with favorable weather conditions, are offering hope for the survival of not only monarchs but also other butterfly species.
As part of ongoing conservation initiatives, the zoo plans to attach radio transmitters to monarch butterflies to track their migration to Mexico. Meanwhile, dedicated enthusiasts like Epp continue to nurture caterpillars and chrysalises, emphasizing the importance of collective action in protecting biodiversity and fostering harmony with nature.
