Ephemeroptera, Plecoptera, and Trichoptera (EPT)
The Illinois Natural History Survey (INHS) maintains some of the largest
and most historically significant collections of the aquatic insect
orders Ephemeroptera, Plecoptera, and Trichoptera (EPT) in North
America, groups that have long been recognized as containing some of
the most sensitive indicators of biotic integrity in flowing water
ecosystems. Efforts to build the collection began in the 1860's and
continue to the present. The INHS' considerable holdings of type
specimens and other historically significant material for North
American EPT species results in a heavy demand for loans of specimens
and requests for information on the distribution of these
collections.
