The bees live alone and do not seem to socialize in any way, so this is not a “network” or “city”. The study says “aggregation” which is more appropriate.
"where they live out their entire lives below ground, building nests, raising young, and going mostly unnoticed." How do they feed?
And later the article contradicts this by saying they go above ground.
I'm confused.
Leave them alone
This is the study itself, which is much better, including photos of the equipment in the cemetery: https://link.springer.com/article/10.1007/s13592-026-01256-6
The only illustration in this article is a photo of a bee, not the cemetery, and when I turned my adblocker off the white spaces I thought might be images are all the same advert about apnea with a guy lolling around in bed with his mouth agape.
