Cornell researchers estimated 3–8 million Andrena regularis bees living underground beneath East Lawn Cemetery near Cornell Orchards, using emergence traps to count and arriving at 5.5 million as a midpoint. The finding underscores how cemetery grounds can host massive, understudied ground-nesting bee populations and highlights how nearby orchards provide forage, reinforcing cemeteries as biodiversity hotspots.
Researchers counting 3–8 million bees at East Lawn Cemetery in Ithaca, NY, estimate an average population of 5.5 million ground-nesting Andrena regularis. Using emergence traps over ~6,000 square meters, the study found males emerge first in April and highlighted nearby Cornell Orchards and sandy soil as key factors supporting this large, pesticide-free population. The work underscores cemeteries as biodiversity hotspots and pollinator habitats, and it launches a global citizen-science effort to document other ground-nesting bee populations.
Cornell researchers estimate a 5.5 million-strong colony of solitary mining bees (Andrena regularis) beneath East Lawn Cemetery near Ithaca, spanning about 1.5 acres. Using emergence traps in spring 2023, they documented one of the largest bee aggregations on record, aided by undisturbed soil and nearby floral resources.
Scientists discovered a massive underground colony of ground-nesting bees (Andrena regularis) beneath East Lawn Cemetery in Ithaca, New York, estimating 3.1 to 8 million bees emerged in a single season—enough activity to rival hundreds of honeybee hives—highlighting the crucial role of solitary bees in pollination and biodiversity and underscoring cemeteries as overlooked habitats that deserve protection; the study notes low parasitism and timing patterns in bee emergence that aid survival.
Researchers from Cornell estimated about 5.56 million ground-nesting Andrena regularis bees emerging from a 6,500 square meter area beneath East Lawn Cemetery in Ithaca, New York—one of the largest bee aggregations on record—highlighting how undisturbed soil in cemeteries can support abundant, often overlooked pollinators.
Researchers find Ithaca’s East Lawn Cemetery hosts about 5.5 million Andrena regularis ground-nesting bees—one of the world’s largest known aggregations—estimated using emergence traps. The study, highlighting cemeteries as biodiversity refuges and the importance of wild pollinators for crops, also details emergence timing, brood parasitism by nomad bees, and a new global citizen-science project to document such aggregations.
