Mark, Leuba, I think I just got the long-awaited answer to this puzzle! I am trying to make the photos. As soon as I can I post here! ;)

Thank you, Joseph!

Thank you, Brian!

What could I say... it's not beautiful, but it's a beauty!

Thank you very much, António!

Thank you Leuba and Maria.

Just unbelievable!

Many thanks for the effort and the tip, Leuba! Yes, very interesting! Tomorrow I'll be back at the place where I found this spotting and check more closely. If I can, I will bring one with me to my house and monitor it for a few days, since, at least apparently the eggs have not yet hatched. Super interesting informations yours. I'm betting it's a wasp!

Hi Mark! About 20mm in length. The bee is ~2mm. Yes, I already considered the spider hypothesis. Nor do I see a wasp handling silk like that, although I have already caught some of them collecting wood shavings, as it seems to have been done in this case. It's a mystery. I think of collecting one (there are a lot of them there) and monitoring it to see what happens.

Hi ornithoptera80. Thank you! I searched a little more and I think I found out. I just entered a suggestion!
