      Are you suggesting that Ground Ivy nectar/pollen is inferior to that which is produced by other flowers?   Please share the source of your pollen/nectar analysis comparing Ground Ivy to other flowers?
      And, what study/data are you drawing from which demonstrates bumblebees visit Ground Ivy because they are desparate, not because they prefer it?

      I would guess they are short of food in early spring and desperate for
      anything with nectar. Often in early spring I have walked around urban
      areas and there is very little of *anything* in bloom (at least on the
      ground; there may be bleeding sap or nectar/pollen in some trees).
