Appendix A. A table of pollinating bee species observed on Echinacea angustifolia heads.

TABLE A1. The identity of all bees seen on Echinacea angustifolia heads during 139 h 40 min of observation in 2004 and 119 h 10 min in 2005. The counts in 2004 and 2005 indicate how many of each taxon was observed in that year. Specimen count shows how many individuals of each taxon we captured. "Sites" indicates the number of populations in which each taxon was observed during 2004 (out of 21) and 2005 (out of 16).
