"Found it by 116th between Avalon an San Pedro by morning glory plants at 330pm 8/20/15."
Observation and photo by Omar Juarez, sent to nature@nhm.org.
I'm not sure what this plant was but there were carpenter and bumble bees all over it. Observation of the bees since the plant was cultivated :-)
Kind of distinctive looking markings at outer edge of wings near tips.
edit: removed 2 images because they were likely different bees
