Photo take at my backyard big wasp flying around a acacia tree flowers about 4 cm long yellow and red colors. more less common in the area.The name "paper wasps" typically refers to members of the vespid subfamily Polistinae, though it often colloquially includes members of the subfamilies Vespinae (hornets and yellowjackets) and Stenogastrinae, which also make nests out of paper. Twenty-two species of Polistes paper wasps have been identified in North America and approximately 300 species have been identified worldwide. The Old World tribe Ropalidiini contains another 300 species, and the neotropical tribes Epiponini and Mischocyttarini each contain over 250 more, so the total number of true paper wasps worldwide is about 1100 species, nearly half of which can be found in the neotropics.
Found on tropical and subtripical areas from Florida , Central America to north Brazil.
The nests of most true paper wasps are characterized by having open combs with cells for brood rearing, and a 'petiole', or constricted stalk, that anchors the nest .Paper wasps secrete a chemical which repels ants, which they spread around the base of the anchor to prevent the loss of eggs or brood.
