Hello Ectemnius,
thank you for your message!
Unfortunately I did not take pictures of the little fly in the background.
But at the same tree wound I was able to take pictures of hornets (
Vespa crabro) and stag beetles (
Lucanus cervus), which eats the juice also.
The tree juice comes from an oak (
Quercus robur).
Kind regards,
Frank
