Stoneflies - Plecoptera: Perlodidae of Gunnison County, Colorado

Isoperla quinquepunctata
Fivespot Stripetail

(Banks 1902)
Updated 29 April 2013
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.

     Abstract: " Life history aspects of the perlodine stonefly Isoperla quinquepunctata (Banks) are reported from the Piceance Basin, Colorado. We wished to discover if the conditions of a spring source would affect the life cycle and relative food habits of I. quinquepunctata as compared to nearby Willow Creek, a typical region small stream site. It is often unusual to find stoneflies directly in a spring source in the southern Rocky Mountains, which had dissolved oxygen concentrations well below 5.2 mg/l (58% saturation), but with flowing water. Isoperla quinquepunctata exhibited a univoltine slow life cycle with extended hatching at both sites. At the spring, while the largest I. quinquepunctata nymphs ingested a variety of food types, they did not switch to carnivory as has usually been reported for Isoperla. Diatoms comprised the majority of the gut contents of nymphs from both the spring and Willow Creek sites, with detritus a more important component at the Willow Creek site. "
