Macronutrient composition in pollen affects development and survival in wild bees

open access: yesPhysiological Entomology, EarlyView.
Small carpenter bees (Ceratina calcarata) were reared on diets formulated with black poplar and dandelion pollen, while closely monitoring developmental metrics, lipid content and survival.
