Aliens have invaded Colorado. Once again, a non-native species has moved into our territory and established a thriving population. In this case, it’s the European Paper Wasp (left). You can read all about it at the Colorado State University Extension website.
In this case, having this new insect in town is a mixed blessing. Although they look a lot like a yellow-jacket, European Paper Wasps aren’t aggressive; they can sting, but they seldom do. On the down side, they’ve been known to go after the sweet juices of ripe fruit such as cherries, and pose a threat to the orchards on the Western Slope.
