Striped cucumber beetle
Acalymma vittatum:
Note deeply impressed elytral striae . . .

That black head gives me pause.
Also I don't see the distinctive black spots on the pronotum. If they are there (one obscured by reflection?), they are pretty anemic. Nomina Nearctica lists 22 Lema species, at least some of which resemble datura*phila. This might be one of those.
