These insects require suitable environmental conditions for nest construction and for the development and survival of their offspring. However, there is little quantitative information on the nesting habitat requirements and preferences of ground-nesting bees. Moreover, there are almost no data on the ...
We confirmed ground nesting bee and sand wasp activity in 7 agricultural sites and 1 recreational park. Soils from 17 bee and sand wasp nests were analyzed for pH, particle size distribution, and carbon and nitrogen content. We visually confirmed that 8 of the nesting bees were sweat bees ...
habitats (see above). However, it is true that in the case of a high abundance ofH. scabiosae, competition for nesting areas may increase up to a level that may lead to the displacement of the other ground-nesting bee species in cities. Third, unlike what often happens for invasive bee...
Do Ground bees sting or bite? Although ground nesting beesare equipped to sting, they will only do so under extreme provocation. In essence, their presence is more of a nuisance than a real threat. Ground nesting bees like to nest in areas with sandy, well-drained soil and limited vegetati...
Insect pollinators are threatened by multiple environmental stressors, including pesticide exposure. Despite being important pollinators, solitary ground-nesting bees are inadequately represented by pesticide risk assessments reliant almost exclusively o
applied to nest cells by many ground-nesting species14. Adult male ground-nesting bees have little exposure to soil as they do not participate in nest construction14, but they might have greater exposure to residues on plants than adult females because they may spend more time in flowers (e....

We quantified nest density and nesting incidence (plot‐level nest presence/absence) of ground‐nesting bees in 12 conventionally tilled and 13 no‐till winter cereal fields in southwestern Switzerland. In each field, nests were quantified in eight belt transects at increasing distances from field ...
