7. Pontoperla katherinae Balynsky 1950

Distribution. The preimago stage of development is common among the benthos of glacial streams and spring rivers of foothill and mountain zones of KBR, but at 500 m below sea level larvae of this species were not found. In the foothill and mountain zone frequently associated with detrital materials in spring and summer, we found 17- 45 specimens per square meter. The average weight of mature larvae (length 7-8 mm) is 6.3-7.1 mg. The larvae are concentrated near the water and substrate interface, on stones washed by water. Most were found in streams with well developed riparian forests ( Yakimov et al 2011 b).
