  <dc:description>This paper describes the life history, distribution, and abundance of &lt;i&gt;Hexagenia&lt;/i&gt; in Lake Erie, as shown by sediment core samples containing preserved &lt;i&gt;Hexagenia&lt;/i&gt; remains dating back to about 1740, periodic sampling of living nymphal populations since about 1930, observations of emergences and mating swarms of adults, and the incidence of &lt;i&gt;Hexagenia&lt;/i&gt; in fish stomachs.  The roles of eutrophication and anoxia, and of oil and heavy metal pollution in the decline, near extinction, and delayed recovery of &lt;i&gt;Hexagenia&lt;/i&gt; in the western basin are also discussed.</dc:description>
