      Yes, I wonder about this. I think they were trapping right by fields full
      of flowers (eg red clover) that were very attractive to bumblebees, so
      perhaps there were proportionally more Bombus in that area to begin with
      than in the areas where you were trapping. ?

      Unless you include the time to wash each Bombus specimen?? (not sure).
