Records of Microlepidoptera from Denmark in 2008 (Lepidoptera).
This article reports and comments on interesting Danish Microlepidoptera collected in 2008, and include remarkable findings from previous years. The classification and nomenclature follow the Danish catalogue (Karsholt & Stadel Nielsen, 1998) which is based on the European checklist (Karsholt & Razowski (eds.), 1996). Two species are reported as new to the Danish fauna: (1) Caloptilia fidella (Reutti, 1853) (Gracillariidae). Several specimens were taken on the Island of Bornholm in two different localities both as adults and larvae. (2) Scrobipalpula tussilaginis (Stainton, 1867) (Gelechiidae). The species has been found as larva and adult at five different localities in Lolland, Zealand and Bornholm. The host plant is Tussilago farfara. No specimens have been found in collections and tussilaginis is regarded as a recent immigrant. Phyllonorycter cerasicolella (Herrich-Schäffer, 1855) (Gracillariidae) has recently been raised to species level by Triberti (2007) and as a consequence of that it is reintroduced to the list. A population of Caloptilia hemidactylella (D. & S.) has been found in South Jutland on Acer platanoides and on Acer campestre. Two tropical species of Pyralidae, Hypargyria metalliferella Ragonot, 1888 and Diplopseustis perieresalis (Walker, 1859), were taken in light traps in Denmark. It is a question whether they are introduced species or migrants. A special list of species with uncertain status is introduced. The Palm Borer, Paysandisia archon (Burmeister, 1880) is reported from one larva and one adult, both found on palms (Trachycarpus fortune) probably introduced from Italy. The total number of Danish Gracillariidae is now 86 and of Gelechiidae 176; this results in a total of 1554 species of Microlepidoptera (families Micropterigidae-Pyralidae) found in Denmark. The total amount of Macrolepidoptera mentioned from Denmark is now 960, bringing the number of Danish Lepidoptera to a total of 2514 species.
