Siebke (1880), Strand (1898) and Kiær (1898) All sawfly larvae are herbivorous (Wagner & published important works on the Symphyta Raffa 1993, Liston 1995, Viitassari 2002), except of Norway, with smaller additions by Strand for those of the Orussidae, which are ecto- and (1900, 1901, 1903). Since then, sawfly research endoparasitic on Buprestidae, Cerambycidae and in Norway has not been continuously performed Siricidae (Kraus 1998). Among the plant feeding and until the last decade, few articles containing sawflies both monophagy and oligophagy are new records were published (e.g. Heibo & Lönnve common, while polyphagy is probably not that 15 Heibo et al.: Sawflies newly recorded from Norway frequent.

Phylloecus linearis (formerly of this study was to report new records of sawfly Hartigia linearis, see Liston & Prous 2014) has a species from Norway. In addition, we comment on wide distribution in Europe (Taeger et al. 2006). the host plants of these sawflies in Norway. The host plant is A. eupatoria L. (Kontuniemi 1960). Agrimonia eupatoria is found north to Trøndelag in dry places in woods and along Material and methods roads (Lid & Lid 2005), but so far, records of P. linearis are only found in coastl areas of southeast The specimens listed below are deposited in Norway. Phylloecus linearis is very similar to the following collections: Zoological Museum, Phylloecus xanthostoma (Eversmann, 1847) and University of Bergen, Norway (ZMUB); Natural correct identification can be challenging. The History Museum, Oslo, Norway (NHMO); characters (relative length of antennomeres and Tromsø University Museum, Norway (TUMN); shape of the sawsheath) (Jansen 1998) used to Senckenberg Deutsches Entomologisches Institut, distinguish P. linearis from P. xanthostoma do Müncheberg, Germany (SDEI); collection of not fit the Norwegian specimens, but fall into an Erik Heibo, Norway (CEHL), collection of Ole overlap zone between those species. However, the J. Lønnve, Norway (COLN), and collection localities where these specimens were collected of BioFokus, Oslo, Norway (CBFO). In the strongly indicate that they are P. linearis.
