Non-honey bees

If monolectic bees could talk, would they be monotematic?
Monolecty means that a bee species uses pollen from only one species of plant or, in the broader sense proposed by Cane, from only one genus of plants. Species which collect from more species/genera, but all belonging to only one plant family, are called oligolectic. Other bees, more generalised in their pollen choices, are called polylectic.

Bees from the genus Macropis collect pollen (and floral oils) from Loosestrife (Lysimachia), which makes them, depending on which definition you use, narrowly oligolectic or monolectic.
