for bees,\u201d Danforth says.<\/p>\n\n\n\n<p>When Hoge began the study, he searched the scientific literature for information on <em>A. regularis<\/em> and found the most comprehensive and useful article dated to 1978, which created an opportunity to more fully describe the bee\u2019s biology.<\/p>\n\n\n\n<p>Like most solitary, ground-nesting bees, female <em>A. regularis<\/em> dig subterranean nests and lay eggs in brood cells provisioned with pollen and nectar. The eggs hatch into larvae and develop into adults underground.<\/p>\n\n\n\n<figure class=\"wp-block-pullquote alignwide is-style-solid-color\"><blockquote><p><em>A. regularis<\/em> and other ground-nesting bees are vastly understudied, even though 75% of bees are solitary ground nesters.<\/p><\/blockquote><\/figure>\n\n\n\n<p>\u201cThis species overwinters as adults, which is relatively rare,\u201d says Hoge, \u201cand that\u2019s part of the reason why they come up out of the ground so early in the spring, timed to the apple bloom,\u201d as well as other fruit trees and early blooming wildflowers.<\/p>\n\n\n\n<p>Cornell Orchards, around one-third of a mile away, provides a large resource of blooming flowers in early spring. This might partly explain the cemetery\u2019s enormous population of <em>A. regularis<\/em>, along with the area\u2019s sandy soil, which these bees prefer, Danforth says.<\/p>\n\n\n\n<p>In the study, the authors employed emergence traps, which are small mesh tents that are open on the bottom and sit over less than a square meter of ground. A funnel leads to a glass jar that traps insects.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-1024x576.jpeg\" alt=\"Bryan Danforth, professor of entomology, surveying native pollinators at Cornell Orchards.\" class=\"wp-image-70383\" srcset=\"https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-1024x576.jpeg 1024w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-300x169.jpeg 300w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-768x432.jpeg 768w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-800x450.jpeg 800w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-608x342.jpeg 608w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-304x171.jpeg 304w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-152x85.jpeg 152w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-1184x666.jpeg 1184w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-592x333.jpeg 592w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-296x166.jpeg 296w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-1264x711.jpeg 1264w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-632x356.jpeg 632w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-316x178.jpeg 316w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-400x225.jpeg 400w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-200x113.jpeg 200w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select-100x56.jpeg 100w, https:\/\/alumni.cornell.edu\/cornellians\/wp-content\/uploads\/sites\/2\/2026\/04\/2015_0678_027_select.jpeg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"rkv-image-credit\">Jason Koski \/ Cornell University<\/figcaption><figcaption class=\"wp-element-caption\">Danforth in Cornell Orchards, which is a half-mile from the cemetery.<\/figcaption><\/figure>\n\n\n\n<p>\u201cYou capture a whole community of animals coming out of the ground with this approach,\u201d Danforth says.<\/p>\n\n\n\n<p>The researchers set 10 traps between late March and mid-May 2023.
