Hi,
This evening (dark and windy) I came across two rather big (especially #1) ovipositing yellow Tephritids. Superficially they recalled Acidia cognata but weren't.
#1: Two of them were busy on a small young Sunflower plant that was already bothered by Aphids and now received eggs into the stem.
#2: One specimen (a really fat one) laid several eggs into developing fuits of a Lonicera shrub.
First I was surprised to find so different host plants, but with the pics on the screen I realized that the flies obviously belonged to different taxa. So I am very curious to learn more about them!
Many thanks, Sundew

This is #1:

This is #2:

#1 looks like genus Strauzia (stem miner of composites like sunflowers that we have in North America) but I have no idea of the distribution of the genus....

That's interesting - thanks, Steve! Let's wait for Valery's opinion...

The first is indeed, a Strauzia sp. (what does thin purely North American species do in Berlin???) and the second is Myoleja lucida, a honeydew fruit fly.

---

That confirms my conclusions that I meanwhile had gained by literature study! So I have found a neozoon indeed. We already fight American Compositae neophytes (Ambrosia), now the next pest associated with Composites comes in sight. Nevertheless it is a lovely fly...
Thanks also for Myoleja ID, it is another taxon new to me. I really become a Tephritid freak! Can't wait for the next "safari" around our house...
Best wishes, Sundew

Here's a male from Ohio showing pretty well developed 2ndary sex characteristics

Hello,

This male also belongs to Strauzia longipennis, the species photographed by Sundew.
