Yes. These beetles are having sex with a beer bottle.
Beer bottles are big, brown and shiny and that is how this male beetle likes his females to be, and these are bigger and shinier than any female beetle could be.
And probably don’t have 20 different pairs of shoes, talk in circles/riddles and are also probably not an hour or so late because they were taking too much time looking after their appearance.
They are just there. And they might get them drunk too.
