Hi, could this be
Euxesta? Found today in my garden in Vienna.

I guess if the genus is correct it can only be
E. pechumani - an introduced species from America?
Edit: Just found out that fauna-eu is out of date regarding that genus. In a 2018 publication,
E. notata was described from Lower Austria. I have a male, so what are the distinguishing features here?

I think
Euxesta pechumani is correct. The dark crossband is supposed to be shorter in
E. notata.

I do agree with John, it is pechumani,
Males, however, have some variation of the wing pattern, and we have both
pechumani and
notata throughout Central Europe.
Females of
E. notata clearly differ in the golden yellow tergite 5 (whereas in pechumani it is dark brown and greenish subshining)

Thanks for the confirmation. That would mean I found a new species for Austria in my garden :-)
Female would have been easy, how do the males differ? Here another photo, not i
n situ this time...

According to the original description, the dark spot closer to the base of the wing is larger in
Euxesta pechumani than in
E. notata.
In the northeastern United States
E. notata is common. I have never seen
E. pechumani and photos are much less common. In Europe the ratio seems to be more even.
