Researchers Discover 5.5 Million Bees Nesting in Soil of Ithaca Cemetery — A Stunning Find That Changes What We Grasp About Urban Pollinators

When news broke about millions of bees nesting beneath a cemetery in Ithaca, Modern York, it wasn’t just entomologists who took notice—it sparked a quiet conversation in communities across the country about what lies beneath our feet in the places we visit most often. For residents of Austin, Texas, a city where live oaks shade historic cemeteries and spring wildflowers bloom along Barton Creek, the discovery hits close to home. Ground-nesting bees aren’t just a curiosity in upstate New York; they’re part of the ecological fabric here too, quietly pollinating native plants in Zilker Park, along the Ann and Roy Butler Hike-and-Bike Trail, and in the older sections of Oakwood Cemetery where families have gathered for generations.

The study conducted by Cornell University researchers in 2023, published in the journal Apidologie, focused on Andrena regularis, a solitary ground-nesting bee species. Unlike honeybees that live in hives, these bees create individual burrows in dry, sparsely vegetated soil—conditions often found in older cemeteries where groundskeeping is minimal and pesticide use is low. Over six weeks, scientists used emergence traps to estimate that approximately 5.56 million of these bees inhabit the East Lawn Cemetery in Ithaca, spanning roughly 6,500 square meters. To put that in perspective, a typical honeybee colony contains about 30,000 bees—meaning this aggregation is equivalent to over 185 honeybee hives concentrated in a single urban green space.

What makes this discovery particularly significant is its historical depth. Archival records show that Andrena regularis specimens were collected from East Lawn Cemetery as early as 1935, just a few decades after the cemetery was established in 1878 on former farmland. This suggests the colony has persisted for nearly 90 years, potentially making it one of the oldest known aggregations of its kind. Researchers like Steven Hoge and Bryan Danforth emphasized that such sites, when left relatively undisturbed, can serve as inadvertent refuges for biodiversity—especially significant given that approximately 70% of native bee species in the United States nest underground.

In Austin, similar conditions exist in places like the Texas State Cemetery near 11th and Navasota Streets, where limestone outcrops and native grasses create dry, well-drained soil ideal for ground-nesting bees. The city’s Integrated Pest Management policy, which restricts pesticide use on public lands, further supports pollinator habitats. Local entomologists at the University of Texas at Austin’s Brackenridge Field Laboratory have documented dozens of Andrena species in Central Texas, including Andrena austinensis, a species first described from specimens found in the Austin area. These bees emerge in early spring to pollinate native flora like bluebonnets, Indian paintbrush, and prickly pear cactus—plants that define the Hill Country landscape.

Yet ground-nesting bees face subtle threats. Urban development, soil compaction from foot traffic, and overly manicured landscapes can destroy their burrows. Unlike honeybees, they don’t swarm or defend nests aggressively, so their decline often goes unnoticed. That’s why entomologists stress the importance of recognizing signs of their presence: modest mounds of soil with a pencil-hole-sized entrance, often seen in patches of bare ground during March and April. In cemeteries and parks, leaving some areas unmulched and avoiding heavy irrigation can make a meaningful difference.

Given my background in environmental journalism and community ecology, if this trend impacts you in Austin, here are the three types of local professionals you need to know:

• Native Landscape Ecologists: Look for professionals certified by the Texas Parks and Wildlife Department’s Wildscapes program or affiliated with the Lady Bird Johnson Wildflower Center. They should demonstrate expertise in Central Texas soil types, native pollinator plants, and low-impact land management techniques that preserve ground-nesting habitats without compromising aesthetics.
• Sustainable Groundskeepers for Historic Cemeteries: Seek teams with experience in preserving historic burial grounds—like those working with Oakwood or Texas State Cemetery—who understand balancng preservation with ecology. Ask about their use of integrated pest management, avoidance of soil tilling near known bee activity zones, and willingness to designate protected nesting zones during emergence season (typically March through May).
• Urban Entomology Consultants: Prioritize individuals affiliated with UT Austin’s Entomology Collection or Texas A&M’s Urban and Structural Entomology unit. They should offer site-specific assessments using non-invasive methods like visual surveys or emergence trapping, provide clear documentation of bee species present, and recommend conservation strategies tailored to Austin’s limestone soils and seasonal rainfall patterns.
