Paper Wasp (family Vespidae): We can’t say for sure from this beautiful photo, but believe this is a European Paper Wasp (Polistes dominula). The almost all orange antennae are diagnostic for this species. They are native throughout Eurasia but were introduced in the 1980’s (or earlier) and are now found across the US and Canada. The adults, like other paper wasps, feed on nectar from flowers and other sugary liquids. They use their carbo-fueled energy to prey on other insects, which are chewed up and fed to their growing larvae. Only females are able to overwinter to start the next season’s generation.
