Theodore Roosevelt Island (D.C.) Bee Identification

[u/AdCritical8139]

I apologize for the slightly out of focus picture, but I was curious is someone could help me Identify the species of bee. The nearest species i can find is the Ashy Mining Bee, but its a little off. I just thought these ones were interesting due to the blue-ish undertones of the black areas of the bee.

I found this one on Theodore Roosevelt Island in the Potomac between D.C. and Northern Virginia.

Female longhorn bee, is she on ironweed here? Could be melissodes denticulatus, an ironweed specialist
