B, 34, 45-50.Emergence traps and Malaise traps used at 12 sites in the Dovrefjell National Parkcaught 24 species of adult stoneflies. Their relative abundance and the number of siteseach species were collected at, showed that 13 species, Arcynopteryx compacta, Diurananseni, Isoperla obscura, Brachyptera risi, Amphinemura standfussi, A. sulcicollis,Nemoura cinerea, Nemurella pictetU, Protonemura meyeri, Capnia atra, Leuctrafusca,L. hippopus and L. nigra were widespread and common in the National Park. Theremaining II species had a restricted distribution, but may be locally abundant. Diurabicaudata, Dinocras cephalotes, Siphonoperla burmeisteri, Amphinemura borealis,Nemoura avicularis, and Capnia pygmaea were collected at one site only.John O.
