The Lamp Lab is back on the hunt for nuisance black flies during summer, 2014! Our goal is to refine our range estimate of the black fly problem, and to determine the main larval habitat. Last year, with considerable help from resident volunteers, we collected and identified over 400 flies as Simulium jenningsi, a species whose larvae we found only in the Potomac River and Antietam Creek. This year we will collect adults throughout the season at a number of places, but we need your help to verify that the flies we collect are the same species that are hurting residents. We plan to provide collecting kits to Judy Warner (founder of Washington County Gnat Fighters) for distribution - let us or Judy ( firstname.lastname@example.org) know if you can help with collecting flies. We will also collect larvae from large rivers around the area, particularly the Potomac River. If you see our grad students and technicians swinging insect nets in Washington County, honk!
