In August 2014, a team of eight persons carried out an inventory of Hymenoptera, mainly the parasitoid wasps and sawflies, on the island. Sampling was done with Malaise traps for a period of 22 days, complemented with vegetation sweeping, branch shaking and opportunistic handpicking during a five day sojourn. As a result, about 200 species of parasitoid wasps and 14 sawflies are reported for Stora Karlso for the first time. Eleven species are reported as new to Sweden: The sawfly Athalia cornubiae Benson, 1931, the gasteruptiid Gasteruption opacum (Tournier, 1877), the diapriid Spilomicrus rufitarsis (Kieffer, 1911), the eulophid Entedonomphale bulgarica Boyadzhiev & Triapitsyn, 2007, the braconids Bracon rozneri Papp, 1998 and Gnamptodon decoris (Forster, 1862), and the ichneumonids Bathythrix maculata (Hellen, 1957), Heterischnus filiformis (Gr...

The knowledge on the sawfly fauna in Norway has been a subject for very little attention for many decades. Most of the faunistic works concerning this insect group was published from 1880 to 1920. The main publications from this period is: Siebke (1880), Schoyen (1880, 1887), Kiaer (1892, 1893, 1895, 1898) and Strand (1898a, 1898b, 1900, 1901, 1903, 1906, 1912, 1919). In resent time work has been carried out on Xyelidae, Pamphiliidae, Siricidae and Xyphidriidae (Midtgaard, 1987, 1988). Nuorteva et al. (2005) gives a species list from the Ostfold County with many new additions to the fauna. Some Norwegian species was also included by Anderson (1962).Sawflies were surveyed for the 2006 Norwegian Red List (Kalas, et al., 2006). A total of 232 species was evaluated for listing, of which 38 are on the 2006 Red List.For the last ten ye...

The pronotum is exceptionally large and its hind margin is nearly straight. They are mostly black or dark coloured, with or without narrow yellow bands. The larva lives in the stem of various woody angiosperms, herbaceous plants, or grasses. The majority of the species are Holarctic and more than 100 species in three tribes and 12 genera are known (Viitassari 2002). So far only eight species have been recorded from Norway: Hartigia xanthostoma (Eversmann, 1847), Cephus spinipes (Panzer, 1801), C. nigrinus Thomson, 1871, C. pygmeus (Linnaeus, 1767), C. brachycercus Thomson, 1871, Trachhelus troglodyta (Fabricius, 1787), Calameuta fi liformis (Eversmann, 1847) and C. pallipes (Klug 1758) (Strand 1889, Nuorteva et al. 2005). Here, Janus luteipes (Lepeletier, 1823) is recorded in Norway for the fi rst time.

Information on its biology and habitat choice is given. C. vagus is an overlooked species that must be considered rare in Norway.

Both genera belong to the large subfamily Tenthredininae (Viitasaari 2002), that contains most of the large and colourful tenthredinids. A number of species are carnivorous as adults, and attack smaller insects. Unlike most other sawflies number of tenthredininies are polyphagous, feeding as a larva on a wide range of host plants.

The first specimen, a male, was collected on 30 May 2012 (leg. S. Olberg, coll. BioFokus). Three days later, a few imagines where found on the same locality and also nymphs where found in the water body at the bottom of the pit. The following days and weeks, dozens of imagines where observed by several persons visiting the locality.

Well-known groups include ants, bumblebees, bees, predatory wasps, parasitic wasps and sawflies. The name Hymenoptera refers to their membranous wings, which are almost film-like. The Hymenoptera vary in size from 0.2 mm to 10 cm, and include some of the smallest insects that exist.

Arten er i Norge kun kjent fra to steder, nemlig Tafjord og Sunndalen i Møre og Romsdal, og er derfor den eneste av våre dagsommerfugler med en ren vestlig utbredelse. Den var derfor betraktet som en godbit for samlere, inntil Direktoratet for Naturforvaltning (DN) vedtok å frede den mot innsamling i 1989. Denne artikkelen handler om da Erik var på leting etter bergjunker oppunder Jostedalsbreen i slutten av juli i fjor. Istedet fant han mnemosynesommerfugl for første gang i Sogn og Fjordane.

Also the gasteruptiid Gasteruption opacum (Tournier, 1877) is reported new to Sweden based on a record from inventory by NJ in 2013. This demonstrates how the knowledge of Swedish biodiversity can be substantially augmented by a short and intensive collecting expedition. We strongly recommend that other places in the country be subjected to similar efforts.
