In the Galapagos Islands, invasive wasps negatively affect the local fauna through competition with native predators.These wasps also pose a risk to humans because of their stings.Thus, it is important to constantly survey these insects.Currently there are three species of vespids known from the Galapagos: two social species are invasive, while a solitary species is cryptogenic.After structured sampling using malaise traps, hand nets, and pan traps on most of the islands of the archipelago, and a review of related collections, the distribution of Brachygastra lecheguana is expanded to Genovesa Island; precise localities and vegetation zones are recorded for Polistes versicolor; and updated information on the distribution of the cryptogenic solitary vespid Pachodynerus gaullei is provided.
