Abstract

Based on historical records in the collection of National Museum of Natural History, Smithsonian Institution, Washington, D.C., 18 species of Dytiscidae have been collected on Plummers Island, Maryland. This represents 21.4% of the known Maryland dytiscid fauna. From 1903–1932 to 1960–1970, collection records show a turnover of 50% in the species composition of dytiscid beetles of the site. Agabetes acuductus (Harris), a species of special concern, has been collected twice on the Island.
