sweet foods and as such may fly near food when people are eating. Median wasps are easily scared off and do not usually become aggressive. This species is more likely to be seen as a pest when it invades a new area due to its impact on the environment. One example is a median wasp that has been spotted in New Zealand. If the wasp becomes widespread and feeds on native flies, moths, and nectar it will compete for resources with other species. Its large size may also cause alarm in new areas.
