Summer Azure butterflies gleaning food from the surface of leaves?

A few adult Summer Azure butterflies appeared to be gleaning food from the surface of leaves over a period of a few days. Maybe it was nectar and/or pollen that had fallen from nearby trees? Or, honeydew from aphids? Clouds of pollen were visible during the preceding days. And, the Tulip Trees were blooming. Anecdotal information indicates that Tulip Trees generate significant quantities of nectar. Observations of the butterflies are attached below. They were exclusively on Wild Bergamot and Southern Mount Mint plants at the edge of the yard.
