White snakeroot (Ageratina altissima) is an incredibly beneficial plant, particularly for insects. One of its greatest appeals is the nourishment it provides to bees, moths, and flies during the autumn season. As the plant blooms late in the year when many other flowers have faded, it becomes a vital source of sustenance for these pollinators.
The late blooming nature of white snakeroot makes it a crucial resource for insects, especially bees. During the autumn months, bees may struggle to find enough food as the availability of nectar and pollen decreases. However, white snakeroot offers a much-needed source of nourishment, allowing bees to continue their important work of pollinating other plants. This not only benefits the bees themselves but also helps to ensure the reproduction and survival of a diverse range of plant species.
In addition to bees, white snakeroot also attracts moths and flies seeking sustenance. Moths, in particular, play a vital role in the ecosystem as they are important pollinators, especially for night-blooming flowers. The late blooming flowers of white snakeroot provide a valuable food source for these nocturnal pollinators, enabling them to continue their crucial role in plant reproduction.
Another interesting aspect of white snakeroot is its relationship with flies. Flies are not often seen as beneficial insects in the garden, but they too can play a role in the ecosystem. Flies are attracted to the flowers of white snakeroot, where they not only feed on nectar but also lay their eggs on the leaves. These eggs will then hatch in the spring, contributing to the life cycle of flies. While this may not seem directly beneficial to humans, it is a fascinating example of the interconnectedness and diversity of life in nature.
Furthermore, white snakeroot can also serve as a host plant for certain butterfly species. For example, the caterpillars of the white snakeroot borer moth (Papaipema sp.) feed exclusively on the leaves of white snakeroot. By providing a specific food source for these caterpillars, white snakeroot supports the life cycle of these beautiful and important pollinators.
White snakeroot is a highly beneficial plant, particularly for insects. Its late blooming flowers provide much-needed nourishment to bees, moths, and flies during the autumn months when food sources may be scarce. Additionally, white snakeroot serves as a host plant for certain butterfly species and supports the intricate web of life in the ecosystem. By including white snakeroot in gardens and landscapes, we can contribute to the well-being and diversity of insect populations, ultimately benefiting the entire ecosystem.
