Photographed in Cambridge, Massachusetts, on the Harvard University campus, by Harvard University, Dept. of Environmental Health and Safety entomologist/environmental biologist, Dr. Gary Alpert, this image depicted a mature Bald-faced hornet, Dolichovespula maculata, nest. The nest had been built by its colony up under the cornice of a museum building, abutting the capital of a Corinthian column. Bald-faced hornets are common in both wooded and urban areas in New England. Queens start a new nest each spring after the weather warms up in late April or May. D. maculata create large arboreal nests with a thin paper outer layer. The queen finds loose bark, and other paper strips to start a small nest into which she places her eggs. She adds saliva to the paper bark and forms a smooth carton. When painted wood is used to make carton, you can see the color on the outside of the carton nest. See PHIL 9814 or a view of this hornet.
