TSN 103045
Locations Collected
This is the most common and abundant Isoperla species (Szczytko and Stewart 1979). The Illinois Natural History Survey has a specimen in their data base from Iola on the 15th of June 1937. This is an interesting historical note because Iola and the Gunnison River nearby were flooded by Blue Mesa Reservoir until the drought in the 2000's exposed Iola again for a while.
This species is rarely referred to as Isoperla 5-punctata, a translation of I. quinquepunctata.
Notes
Older publications may refer to this species as Cloroperla quinquepunctata or Isoperla patricia.
