A survey of the adult odonate fauna of a small woodland pond in Pope County, Illinois, was conducted during 1983--·1984. Twenty-four species were collected including Aeshna mutata and Anax longipes. In addition, Libellula vibrans was collected in 1982, and Aeshna sp. (probably u. umbrosa) observed the same year but not collected.
