Here we see a pleasing assortment of wasps constructing new colonies with naught but hexagons and saliva.
In the second image: "A young paper wasp queen (Polistes dominula) is founding a new colony. The nest was made with wood fibers and saliva, and the eggs were laid and fertilized with sperm kept from last year. Now the wasp is feeding and taking care of her heirs. In some weeks, new females will emerge and the colony will expand. The timespan between the older and more recent photos is about one month."
