Polistes gallicus is a species of paper wasp found in a region from the Alps south into northwest Africa and east to Croatia and Corfu. It can live in a range of temperatures including warmer climates and cooler regions north of the Alps, with nests created in these various conditions. A social insect, the species uses an oral secretion to construct its nests, which consist of a combination of saliva and chewed plant fibers. This structural mixture physically protects the nest from various harsh elements and from weathering over time. Like other members of the subgenus Polistes, P. gallicus has recognizable bright yellow and black markings. It has a smaller body than many others from the genus that overlap in range. This P. gallicus individual was photographed in Bavaria, Germany.Photograph credit: Reinhold Möller
