Abstract
During 1994-1995 extensive field work was conducted in southeastern Mi chigan in an attempt to assess the species population and composition of libellulid dragonflies. Additional field work was conducted on drag onflies from southwestern Ontario migrating into southeastern Michigan . Comparisons were made with the species listed for this area 37 years earlier in Kormondy (1958) anticipating changes due to wetland reduct ions and the effects of pesticides. With one exception, all species li sted in Kormondy were observed. Additionally, one species, unknown fro m this area as of 1958, was encountered.
