I thought this was a grey hairstreak at first, but as it was flitting about, the wings seemed to be almost light blue in color, which surprised me. I managed to get a shot of it after it landed, and the patterning seems different from the usual hairstreaks I see around here (though I don’t necessarily pay close attention).
For further details, this was at a nursery nectaring on a planted Buddleia marrubifolia before it took off and landed on the ground.
