|Description:||Photographed in Concord, Massachusetts, May 2006, by Harvard University, Dept. of Environmental Health and Safety entomologist/environmental biologist, Dr. Gary Alpert, this image depicted an anterior view of a Bald-faced hornet, Dolichovespula maculata. Though named as a hornet, this wasp is not a true hornet from the genus, Vespa, but is more closely related to the yellow jackets, and is a member of the genus Dolicovespula.

D. maculata create large arboreal nests with a thin paper outer layer, and can be recognized by their black and white color markings, especially the white areas on their face. These large wasps will sting when defending their nest, or when defending themselves against perceived harm. Stings from these insects can induce anaphylactic shock in susceptible individuals, and therefore, control of their populations need be left to professional control specialists. They are widespread across the United States. See PHIL 9815 and 9816 for images revealing structural details of this insect’s nests.
