Found on 31. Mai 2017 near Kerzers, Switzerland, 437 m, on a woodden armrail, waving its wings and abdomen. Size: 5 mm Could it be an Euxesta sp.? Maybe E. notata? Kind regards, Ov Ocellar view attached the following image:  [98.26Kb] Edited by Ocellar view on 06-06-2017 12:05 |

I think Euxsta notata. According to the key by Curran (1935) costalis has a larger wing spot. |

Thank you John and Paul! It is great to have the opinion of experts. So it is either an invader or the similar native. Since the wing spot rather speaks for E. notata, I assume this to be the case. Thanks again and kind regards, Ov Edited by Ocellar view on 07-06-2017 08:17 |

All Euxesta are native to America. E. costalis was described from the West Indies, notata from the United States. |
