“…Leafcutter bees are cavity nesters and use almost all unpredictable sites for constructing nest tubes 39,40 . Since they are above-ground nesters, they are less affected by the soil, which is often polluted and compacted in urban places and agricultural landscapes 11,41 .…”

“…In the present investigation, we did not quantify them. Natural nesting sites of leafcutter bees can be any unpredictable cavities or crevices in any arti cial or natural materials 39,40 . Two of the authors' (PAS and AK) observations (N=21) in parts of southwestern USA (PAS) and south India (PAS & AK) are that the nesting places of leafcutter bees are between 0.8 m and 17 m from the leaf sources (PAS & AK, Unpublished).…”

Pollinator conservation is a global priority. Efforts are taken to restore pollinators by improving flower resources, a crucial driver of pollinator diversity and population. It gave a facelift to gardening and landscaping supply chains, which introduced lists of bee-friendly plants and bee hotels, yet, desirable results seem distant. One shortcoming of the present schemes is the lack of a cohesive planning for nesting opportunities and nesting provisions for the wild solitary bees, the crucial pollinators of crops and wild plants. We tested whether the world’s most favourite ornamental plant, Rose (Rosa chinensis Jacq.) – a hitherto unlisted bee-friendly plant – can aid conserving leafcutter bees, which require fresh leaves for constructing nest cells. We surveyed 2,360 Rose plants in 136 sites in rural and urban places and lowlands and highlands of south (8oN – 12oN) and northeastern India (26oN-27oN) for the characteristic notches the bees leave on foraged leaves. Potted Rose plants were sprayed with the contact pesticides to study the effect of pesticide on bee foraging of leaves. Broods constructed by the Rose leaves were reared to examine the brood success rate. About a quarter of all the Roses surveyed had the notches of leafcutter bees on the leaves. However, the proportion of cut Roses varied considerably among and between sites. Bees used Roses heavily in cities and lowlands over villages and highlands. Selection of plants was negatively associated with pesticide treatment. Brood success rate was 100%. Rose flowers do not support bees, but Rose leaves do. We recommend Rose plants in pollinator conservation and restoration schemes.

“…However, the response of bees to urbanization has often been illustrated positive by recent studies 41 – 44 , and our findings support it. Leafcutter bees are cavity nesters and use almost all unpredictable sites for constructing nest tubes 45 , 46 . Therefore, they are less affected by the soil, which is often polluted and compacted in urban places and agricultural landscapes 13 , 47 .…”

Pollinator conservation is a global priority. Efforts are taken to restore pollinators by improving flower resources, a crucial driver of pollinator diversity and population growth. It helped gardening and landscaping supply chains, which introduced lists of bee-friendly plants and bee hotels, yet, desirable results seem distant. One shortcoming of the present schemes is that they lack a cohesive planning for nesting opportunities and nesting provisions for wild solitary bees, the crucial pollinators of crop and wild plants. We tested whether the world’s popular ornamental plant, rose (Rosa chinensis Jacq.)—a hitherto unlisted bee-friendly plant—can aid in conserving leafcutter bees, which require fresh leaves for constructing nest cells. We surveyed 2360 rose plants in 136 sites in rural and urban places and lowlands and highlands of south (8°N–12°N) and northeastern India (26°N–27°N) for the characteristic notches the bees leave on foraged leaves. We reared brood constructed with rose and non-rose leaves to examine the brood success rate. About a quarter of all the roses surveyed had the notches of leafcutter bees on the leaves. However, the proportion of cut roses varied considerably among sites. Bees used roses much higher in urban areas and lowlands than in rural areas and highlands. The selection of plants was negatively associated with pesticide application. The brood success rate was 100% for the brood that was constructed by the leaves of rose and non-rose plants. Rose flowers do not support bees, but rose leaves indeed do. We recommend rose plants in leafcutter bee conservation and restoration schemes, particularly in urban environment.
