In terms of foraging, these bees are highly adaptable and can be found visiting a wide range of flowers in various habitats, from meadows to woodland edges.
Interestingly, studies have shown that northern amber bumblebees often interact with other pollinators like honey bees (Apis mellifera) and solitary bees (Halictidae family), but they tend to avoid competition by foraging at different times. This behavior is known as “temporal partitioning,” allowing them to coexist peacefully.
Within colonies, the social structure of northern amber bumblebees is relatively complex. A single queen establishes the colony in the spring, and workers (female bees) perform various tasks like foraging, caring for young, and defending the nest. As the colony grows, a new queen is produced towards the end of summer to ensure the survival of the species.
When it comes to managing these colonies, gardeners can create a bee-friendly environment by planting a diverse range of flowers that provide nectar and pollen throughout the growing season. This not only supports the northern amber bumblebee but also other pollinators, contributing to a thriving ecosystem.
Queen Bumblebees and Colony Formation
At the heart of every bumblebee colony is its queen, and for northern amber bumblebees, her survival is crucial to the species’ future. These remarkable females are responsible for starting new colonies each spring, ensuring the continuation of their genetic lineage.
In late winter or early spring, a solitary queen will emerge from hibernation, searching for a suitable nesting site. She will then begin building her colony by laying eggs and caring for the young. This initial phase is critical, as the queen’s health and success in establishing a strong colony directly impact the species’ overall population.
The importance of queen bumblebees cannot be overstated; their role is often likened to that of a “founder” of new colonies. Without them, northern amber bumblebee populations would likely dwindle rapidly. For instance, studies have shown that queens account for up to 90% of successful colony establishment.
To support the survival and success of these vital individuals, it’s essential to provide suitable habitats and food sources. Planting bee-friendly flowers, such as wildflowers or herbs like oregano and mint, can significantly aid in their foraging efforts. By taking simple steps like these, you’re contributing directly to the well-being of your local northern amber bumblebee population and its queens.
