Figure 8.

The interaction phenology (including all bee visits) of plants (A) that Osmia spp. visited, and of Osmia spp. (C) over the summers of 2008 and 2009. The weeks correspond to biweekly sampling dates, beginning in early May and ending in mid-October. The length of the segments demonstrates the interaction duration for that species, whereas the height represents the abundance of interactions and their fluctuations over time (plotted on the x-axes). (B) This quantitative bipartite visitation network was constructed from collections of Osmia spp. on flower species. The boxes (nodes) on the left represent plant species and the boxes on the right represent Osmia spp. The height of the boxes is the proportional number of interactions. Lines connecting plant and bee species represent floral visitation events and are scaled by abundance.
