Xanthogramma pedissequum

Looks good to me! Thanks for that.

It´s probably pedissequum because the dark area below the stigma spreads markedly below R2+3. And there don´t appear to be woods near your location
This is worth a look

and here´s my observation of similar which has
been identified as X. stackelbergi on the Danish ispot, where it seems to be more established and accepted as a distinct species. The last pic shows the dark area below the stigma ending abruptly at r2+3

there is possibly nothing conclusive here, and we await further updates on these species, but something to consider at least
