Cape Cod Sanctuary Reveals Late-Season Pollinator Activity

A recent observation at Audubon’s Long Pasture Sanctuary in Cummaquid, Massachusetts, revealed a thriving population of hoverflies actively pollinating late-blooming asters, offering a reminder of the importance of all pollinators as monarch butterfly migration slows.

Yesterday, a visit to the sanctuary’s meadow path highlighted the ongoing activity despite the diminishing presence of monarch butterflies, whose favored milkweed plants are dispersing seeds. While initial hopes were for a final monarch sighting, a closer examination of the blooms revealed numerous hoverflies diligently collecting pollen. These insects, often mistaken for bees, play a crucial role in pollination, particularly as other pollinator populations decline.

Hoverflies are distinguished from bees by having only one set of wings and different eye structures, though their tail markings can appear similar. Unlike bees, hoverflies do not sting, but contribute significantly to the ecosystem as pollinators. Understanding the differences between these insects is important for conservation efforts, as highlighted by organizations like the Pollinator Partnership. The Long Pasture Sanctuary, a vital part of Mass Audubon, offers diverse habitats for a variety of species, as detailed on their sanctuary page.

The observation serves as a reminder to look closely at the natural world, as appearances can be deceiving, and every creature plays a role in the ecosystem. Sanctuary officials will continue to monitor pollinator activity throughout the fall and winter months to assess the overall health of the local ecosystem.
