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.
