Notulae odonatologicae , Volume 2 - Issue 9 p. 152- 153
An extensive field survey of Odonala of Illinois in 1984-1986 resulted in a number of new state records (including some range extensions), and a re-discovery of some species that have not been collected since 1933-1958. In addition to the species collected by the authors, others noted below were discovered in existing collections in the state. According to recent literature (J.G. NEEDHAM & M.J. WESTFALL, 1955, A manual of the dragonflies of North America, Univ. Calif. Press, Berkeley; B.E. MONTGOMERY, 1967, Proc. N. cent. Brcheni. Soc. Am. 22: 121-129; T.E. VOGT&J.E. McPHERSON, 1985. Gl Lakes Emomol. 18: 7-13) the listed species were not known to occur in Illinois. Except where noted, all specimens are in the Illinois State Museum Entomology Collection.
