Biosurvellance: Using a native wasp to moitor for Emerald Ash Borer

Cerceris fumipennis, a native non-stinging wasp, can help entomologists with early detection of the destructive exotic emerald ash borer. This ground-dwelling wasp provisions its nests with buprestid beetles, including emerald ash borer when present. In Maine, Cerceris can only be found during the months of July and August, although it emerges earlier further south.

The Maine Forest Service is currently looking for colonies of this wasp. For those who would like to assist us, here is some information to help you find colonies and report your findings.

August 20th 2009: Cerceris has emerged throughout the southern half of the state. Media coverage has raised awareness of the search for new colonies (and yielded one). One story, featuring video of the wasp and volunteers in action, is found at WCSH6.com (Off-site). A newspaper story from Lewiston Sun Journal can be found here (off-site).

August 4th 2009: The weather has been very cold and rainy, but Cerceris is finally emerging. Colonies are active in southern Maine and are starting to emerge in Central Maine.

May 29th 2009: Naturalist Dick Walton has added to his already stunning video footage of Cerceris fumipennis with new footage and narration (off-site, large file).

September 9th 2008: Cerceris activity has decreased to a minimum. Thanks to all who took the time to look for Cerceris in Maine and who contributed to the success of the first year of this project (more...).

July 14th 2008: Cerceris should be active throughout much of Maine from now until late summer. The best time to look for it is during mid-day on a sunny day (more...).
