According to Thompson (2001) insect visitation may be influenced by spatial and temporal floral displays, and it is also important to consider that constancy exhibited by insects in visiting heterostylous populations could be a result of spatial aggregation by clonal growth and near-neighbor foraging (Husband & Barrett 1992).
