Description of the larva of Isoperla orobica Ravizza, 1975 (Plecoptera, Perlodidae), with notes on ecology and distribution in Switzerland.

The larva of Isoperla orobica Ravizza, 1975, an endemic Alpine species, is described with information about the distribution and ecology in Switzerland. New barcodes were generated to support the association between life stages. The species is associated with springs and spring brooklets. In Switzerland, the species occurs almost exclusively on the southern slopes of the Alps in the cantons Valais, Ticino and Grisons. [ABSTRACT FROM AUTHOR]
