Is this Dioxyna bidentis again - as in my previous post? NW Bulgaria, 12.09.2018 I thought i would post these too, because they are on a different plant - Bidens frondosa, the host that gave them the specific epithet. Original post on iNaturalist with more photos: https://www.inatu...s/16634234

The name probably comes from a different species of Bidens. B. frondosa is native to America and Dioxyna bidentis is European. I had some 3 meter tall Bidens frondosa growing next to my house last summer. They attracted some Agromyzidae but no Tephritidae that I could see. |

Thanks again Val. John Carr, you are right - Bidens frondosa is introduced in Europe. I see records of this fly from several species of Bidens - seems this is its favorite genus of plants :-) Edited by exonie on 04-12-2019 15:43 |
