Hi, could this be Euxesta? Found today in my garden in Vienna. Edited by Carnifex on 28-06-2019 10:27 Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.

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 Edit: Just found out that fauna-eu is out of date regarding that genus.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) Val |

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 in 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. |
