Monolecty in bees was defined a century ago for those species that consistently collect pollen only from the same single species of floral host. Even at the time, the term was considered “a curiosity” with little biological meaning. Here, I review its multiple problems and suggest that its utility would improve if we apply the term monolecty to those bees species that use a single genus (not species) of flowering host.
