Its not a hornets nest its a wasps nest, it even says it in the corner of the pic.
It's a photoshop label.
Il also add that what you (US) call yellow jackets are what we call wasps.
Peace
Yellow jackets are wasps. What they're called sometimes depends on where they are. That's why I referenced entomology.

What a given geographical area calls their critters is cool with me.
It's just important to note that the enclosed-nest critter is more social, more easily enraged and more dangerous to us.
