Dear Travis, I concur with Cynthia. Your observations and photographic skills are awesome. This summer my native Penstemon were black with solitary bees. Best, Joyce Miller, Gresham, Oregon, USA Travis, I read your bee material with great interest! Kudos to you for putting this all together, and for illustrating it not only with very good images but also with your personal observations. Keep up the good work! -CWM
