[5] The same kind of nest expansion has occurred in Hawaii with the invasive western yellowjacket (V. After the emergence of the first brood, these workers take over the duties of foraging for food, feeding the larval yellowjackets and increasing the size of the nest. These colonies can reach into the thousands of individuals late in the summer or early fall and their presence near to people make them a potential danger.

It reached southern California in 1991 becoming part of California's fauna. In some cases, the nests may survive through the winter and reach the next season.
