Researchers discover an underground colony of bees with an estimated population of 5.5 million under a New York cemetery | Emergence dynamics and host-parasite associations in a large aggregation of Andrena regularis (Hymenoptera: Apoidea: Andrenidae) Read…
🐝 A remarkable colony of approximately 5.5 million subterranean mining bees (Andrena regularis) has been discovered in East Lawn Cemetery, Ithaca, New York, spanning about 1.25 acres. This finding, published in April by Cornell University researchers, is one of the largest bee aggregations ever recorded and is vital for local orchard pollination.
🔬 Scientists used specialized traps between late March and mid-May 2023, sampling over 3,000 insects. Extrapolating from these samples, they estimated the Andrena regularis population to be between 3 and 8 million, with an average of 5.5 million individuals.
🌳 Historic cemeteries, like the one established in 1878, are proving to be crucial refuges for urban biodiversity. The mining bee species winters underground as adults, enabling early spring activity synchronized with apple blossom, while also facing ecological dynamics like parasitism from other bee species.
🌍 This discovery underscores the importance of protecting wild bee nesting sites, as 75% of wild bees are solitary and nest underground. Cornell researchers have initiated a global citizen science project to help identify and conserve these vital pollinators in urban environments.
