| About the ImageThe European paper wasp (Polistes dominulus) is a recently arrived invasive species in the United States. First observed in Cambridge Massachusetts in 1980, it has been steadily spreading south and west. European paper wasps are often mistaken for yellow jackets, but are generally not as aggressive (though reportedly they are more aggressive than the native paper wasps, which are being displaced by the invaders). This colony was discovered in between the window and the screen of the Introductory Biology laboratory. | |
