Pictured is a large hornets nest along SR54 in Barnesville.
As the size of a wasp colony grows, new combs are added, and an envelope is built around the cell layers until the nest is entirely covered with the exception of an entry hole. At the peak of its population, the colony can reach a size of 700 workers, which occurs in late summer.
At this time, the queen starts producing the first reproductive individuals. Fertilized eggs develop into females (called “gynes” by entomologists), and unfertilized ones develop into males (sometimes called “drones”). Adult males do not participate in nest maintenance, foraging, or caretaking of the larvae. In early to mid autumn, they leave the nest and mate during “nuptial flights”. Males die shortly after mating. The workers and queens survive at most until mid to late autumn; only the fertilized queens survive over winter.
