High up on the branch of an old tree, hidden among the leaves, a round paper ball seemed to grow larger with each passing week. It wasn’t paper at all, but the work of the Lesser Banded Hornet (Vespa affinis), a wasp known for its bold black body with bright yellow-orange bands and its remarkable teamwork. The nest, smooth on the outside and layered like sheets of brown paper, could grow to the size of a football or more. At the peak of the season, it could shelter hundreds to over a thousand hornets, all buzzing with purpose.
It all began with a single queen. With her strong mandibles she scraped wood into fibers, chewed them into soft pulp and shaped the first fragile walls of her nest. Inside the neat hexagonal cells she laid her eggs. These hatched into larvae, which she carefully fed until they grew into workers her daughters who then took over the hard labor of building, hunting & guarding the nest. The workers, smaller but energetic, made the exposed football-shaped nest bigger & stronger day by day.
The larvae were fed on soft, chewed-up prey flies, caterpillars, grasshoppers, & even other wasps hunted down by the workers. The adults themselves ate differently; they sipped nectar, fruit juices and tree sap, drawing energy to power their fast wings. In return, the larvae produced a sweet liquid reward for the adults, creating a cycle of sharing within the nest.
As the colony grew stronger, the queen shifted her role from producing only workers to laying special eggs that became new queens & males. These young queens, after mating, would leave the nest & search for safe hiding places to spend the winter. When warmth returned, each one could start a brand-new colony of her own. The old colony, however, came to its natural end: workers lived for only 2–3 months, while queens could survive up to a year if they overwintered successfully.
Though the LBH could be fierce if disturbed, their nest told a story of patience, teamwork, & survival. From their striking banded bodies to their carefully built paper castles, every part of their life from nest size to feeding habits, from reproduction to lifespan revealed nature’s clever design, buzzing high.
