This article reports and comments on interesting Danish Microlepidoptera collected in 2011 and include remarkable findings from previous years. The classification and nomenclature follow the new Danish checklist (Karsholt & Stadel Nielsen, in press). Ten species are reported as new to the Danish fauna, most of them collected in light traps, especially in the island of Bornholm: 1) Agonopterix bipunctosa (Curtis, 1850)(Depressariidae) and 2) Monochroa sepicolella (Herrich-Schäffer,
1854)(Gelechiidae): one specimen of each in light traps in Bornholm; 3) Phalonidia udana (Guenée, 1845)(Tortricidae), which has been shown to be distinct from P. manniana (FR.), seems to be widely distributed in Denmark; 4) Aethes fennicana (Hering, 1924)(Tortricidae): three specimens were collected in a light trap in the island of Lolland; 5) Epinotia cinereana (Haworth, 1811)
(Tortricidae), which has been shown to be distinct from E. nisella (Cl.), has been found in several districts but is much rarer than the latter; 6) Wockia asperipunctella (Bruand, 1851)(Urodidae) is recorded from one specimen found in Bornholm in 1984; 7) Sciota fumella (Eversmann, 1844)(Pyralidae) was found in 10 specimens collected in light traps in Bornholm during the first week of July, together with one specimen of 8) Sciota lucipetella (Jalava, 1978)
(Pyralidae); 9) Ephestia unicolorella Staudinger, 1881 (Pyralidae): one specimen was collected in a light trap in western Jutland, and 10) Pseudobissetia terrestrellus (Christoph, 1885)(Crambidae): one specimen of this southern species was collected in a light trap south of Copenhagen in the same night (3th July) as
the two above mentioned Sciota species. We moreover record an imported species, Zelleria oleastrella (Millière, 1864)(Yponomeutidae), which has not earlier been found in Denmark.
The Oegoconia species, which in previous lists was dealt with as O. caradjai Popescu-Gorj & Căpuşe, 1965, has turned out to be O. novimundi Busck, 1915. We can moreover report findings of larvae of Yponomeuta irrorella (Hb.) on Malus, where larvae occurred singly and apart from nests of other Yponomeuta
species. The total number of Danish Depresariidae is now 46, Gelechiidae 178, Tortricidae 387, Urodidae 1, Pyralidae 78 and Crambidae 123. This results in a total of 1584 species of Microlepidoptera found in Denmark. The total amount
of Macrolepidoptera recorded from Denmark is now 967, bringing the number of Danish Lepidoptera to a total of 2551 species. There are moreover 10 species on the so-called observation list, containing species of uncertain status, which was erected in 2009.
