Symmerus nobilis was described from Latvia ( Lackschewitz 1937 ) and has been found in several countries of Central Europe ( Chandler 2004 , Zaitzev 1994 ), but is considered everywhere a rare species. From the well-studied British Isles it was recorded only from one site in Scotland (Glen Coiltie, Easterness) ( Falk and Chandler 2005 ). In the Fennoscandian region, the species was recorded only recently from southern parts of Norway ( Gammelmo and Rindal 2006 , Kjaerandsen and Jordal 2007 ), south Sweden ( Jakovlev et al. 2008 ), the Kivach Nature Reserve in Russian Karelia (two female specimens, Polevoi 2000 ). No former records from Finland. Ecology All collecting records of adults are from broadleaved forests, with the exception of Russian Karelia which lies entirely in the boreal forest zone. The Russian Karelian sites are spruce dominated forests with a high proportion of aspen ( Populus tremula ). The Finnish record is from a herb-rich spruce-dominated forest with aspen, birch, lime and oak ( Quercus robur ). Both the Finnish and the Karelian sites are old growth forests on fertile soils with a high amount of dead aspen wood, in which larvae of the species most likely develop. Larvae live in decaying wood, as indicated by rearing records from beech ( Zaitzev 1994 ). Conservation Red-listed in Finland (VU, Penttinen et al. 2010 ), Norway (VU, Anonymous 2010 , Gammelmo et al. 2010 ) and Sweden (NT, Cederberg et al. 2010 ).
