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.

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 :-)

If you experienced a very sluggish site recently, it may have been because someone tried to upload a maliciuous script by force. It appears to have failed. The visitor was blocked further access.
