New record SWEDEN: 1 ♂, Nybro, Alsterbro, Alsterån, 56.936536° N, 15.920167° E, Trap ID 1008, collecting event 1743, Malaise trap, 16–22 Jul. 2006, leg. Swedish Malaise Trap Project (NHRS). Distribution Estonia, Great Britain, Belgium, Germany, Poland, Czech Republic, France, Austria, Switzerland, Spain, Croatia (Istria), Greece (Crete), Bulgaria, Ukraine (Crimea), Russia (Karachay-Cherkessia), USA (Dominiak & Szadziewski 2010). Biology Larvae of D. flavifrons can be found in tree sap or tree holes. Flight period May–October (Dominiak 2012). Remarks The previous listing of this species as present in Sweden is doubtful as it has only been reported in Rehnberg & Brodin (2010), based on D. versicolor (Winnertz, 1852) as listed in Szadziewski et al. (1997). We were unable to verify previous records.
