A study looking at floral density and pollinators finds that some types of pollinating insects prefer dense flower patches more than others, but that preference can also vary by flower species, too. The complicated findings offer clues to how multiple pollinator species co-exist and compete for floral resources. Shown here is a patch of Monarda fistulosa, one of the flower species included in the study. (Photo by Joshua Mayer via Flickr, CC BY-SA 2.0)
