Taxonomic note.

The taxon ' Tipula persicariae ' was originally described by Linnaeus (1767: 977). The revision of the types revealed, that this species belongs to the gall midges and was placed in the genus Wachtiella Rübsaamen, 1915 [= Wachtliella persicariae (Linnaeus, 1767); Cecidomyiidae : Cecidomyiinae , Dasineurini ]. Soot-Ryen (1942: 74) interpreted ' Sciara persicariae (Linnaeus)' in Zetterstedt (1871) and Siebke (1863, 1870, 1877) as a species of ' Dasyneura ' [recte ' Dasineura ' ( Cecidomyiidae )] and ignored therefore all records of ' Sciara persicariae ' in his list of Norwegian Sciaridae . Frey (1948: 54, 77) states however, that some specimens of ' Sciara persicariae (Linnaeus)' sensu Zetterstedt were interpreted incorrectly and might belong to Bradysia strigata (Staeger) [misidentification]. One specimen in the TMUC collection (belonging to Sciaridae ) was found under ' sororcula Zetterstedt’ (det. Siebke), which - following the synonymy of types - would be Bradysia confinis (Winnertz). We are following Frey (1948) and list under Bradysia strigata (Staeger) all Norwegian records until a final revision of misidentified ' Sciara persicariae (Linnaeus)' sensu Zetterstedt is undertaken.

Ecological note.
