Using emergence traps to study ground-nesting bees: insights from field experiments and advice for future research

The nesting biology of ground-nesting bees is woefully understudied compared to research on bee foraging preferences, despite that over 70 percent of all bee species are ground-nesting bees. This information is desperately needed to better inform conservation actions that address both food and nesting requirements for bees. However, most studies on ground-nesting bee nesting focus on bees that nest in open, bare soil or in large aggregations, thus biasing our subsequent recommendations regarding nesting habitat availability. Emergence trapping is a relatively new methodology to study ground-nesting bees, in which small tents with an open bottom and bottle at the top are secured to the ground to catch emerging insects. Emergence traps allow for the detection of bee nests that may otherwise go unnoticed in dense vegetation or underneath leaf litter.
