Hello,

in summer I watched some flies "hopping" on leaves of Artemisia vulgaris. It looked as if it was a mating display, or only males trying to boot each other out.

If you like, you can download here a short video of my observation (9 sec, 25.8 MB) within the next seven days: https://we.tl/t-3zPtBjbf1B
(If this might be unwanted in this forum, please delete.)

Data: Germany, Lower saxony, Rodenberg, 90 m, garden, 4 July 2019.

Best regards,
Tina.

This is Chrysotus laesus, no doubt about it.

Many thanks, Marc!
Do you maybe also know anything about this behaviour?
