My garden in South west London is full of Digitalis foxgloves ready and waiting for bumble bees but there are zero. My nest box is already full of red masons and the hairy footed flower bees were as usual out in force - males and then females - anyone have any ideas? Barely seen any sign this year.

Brood-site pollination mutualisms are plant–insect interactions where plants provide brood sites for insects that pollinate flowers but imposes conflicting fitness costs as larvae feed on floral tissues, while the plant gains pollination. www.sciencedirect.com/science/arti...

Single-compound floral signaling stabilizes cooperation in an obligate brood-site pollination mutualism

How conflict-prone brood-site pollination mutualisms persist remains a central question in evolutionary ecology.1,2,3,4 We demonstrate that a single, …

Specialization & adaptation in pollen sterol use by wild bees - our new paper in iScience. 56 bee species analyzed to determine which pollen sterols they use. The data suggest an ecological rather than phylogenetic driver of bee sterol composition @rbgkew.bsky.social www.cell.com/iscience/pdf...

Specialization and adaptation in pollen sterol use by wild bees

Sterols are stabilizing components of membranes and hormone precursors in eukaryotes. Honeybees incorporate a subset of pollen-derived sterols into th…
