Bumblebees are social insects that build their nests in various habitats, including underground burrows, abandoned rodent nests, and cavities in trees or buildings. These nests are typically small, with a single queen and a few workers during the early season, growing to include several hundred workers by late summer. The nest’s temperature is crucial for the survival and development of bumblebee larvae and pupae, with an optimal temperature range of 29-34°C (84-93°F).
Effects of Climate Change and Habitat Loss
Rising temperatures due to climate change can cause nest overheating, leading to decreased reproductive success and increased vulnerability to disease. Overheating can also affect the behavior and foraging efficiency of adult bumblebees, reducing their ability to collect nectar and pollen for the colony. Habitat loss is another significant threat to bumblebee populations, as urbanization and agriculture expand, reducing the availability of suitable nesting sites.
