Motýli (Lepidoptera) bývalého vojenského prostoru u Oleška (Česká republika, Ústecký kraj)

Abstract: The lepidopteran fauna of the former military training area near Oleško (Czech Republic: Ústecký Region) was studied in the year 2008. This area is on sandy ground, the predominant habitats are dry Scots pine forests growing on sand. 700 species were recorded, many of them are markedly psammophilous. Some characteristic species are very abundant there, namely on open habitats Aroga velocella (Zeller, 1839), Teleiopsis diffinis (Haworth, 1828), Platytes alpinellus (Hübner, 1813), Pyrausta ostrinalis (Hübner, 1796), Paradrina selini (Boisduval, 1840), Agrotis vestigialis (Hufnagel, 1766), Eilema pygmaeolum (Doubleday, 1847), some other species were only recorded some other species were only recorded individually (Aristotelia brizella (Treitschke, 1833), Helcystogramma lineolellum (Zeller, 1839), Pediasia fascelinella (Hübner, 1813), Lythria cruentaria (Hufnagel, 1767) and Hadena irregularis (Hufnagel, 1766). Elatobia fuliginosella (Lienig et Zeller, 1846), Decantha borkhausenii (Zeller, 1839), Epinotia rubiginosana (Herrich-Schäffer, 1851), Cydia conicolana (Heylaerts, 1874) and Catoptria verella (Zincken, 1817) are characteristic of dry pine forests on sands. Elatobia fuliginosella (Tineidae) is recorded in Bohemia for the first time. Findings of other species are also very interesting from a faunistic point of view (Stenoptinea cyaneimarmorella (Milliére, 1854), Zelleria hepariella Stainton, 1849, Stephensia abbreviatella (Stainton, 1851), Caryocolum proximum (Haworth, 1828), Euscrobipalpa proclivella (Fuchs, 1886), Euscrobipalpa obsoletella (Fischer von Röslerstamm, 1841), Phtheochroa inopiana (Haworth, 1811), Cochylidia heydeniana (Herrich-Schäffer, 1851), Endothenia marginana (Haworth, 1811), Dichrorampha obscuratana (Wolff, 1955), Vitula biviella (Zeller, 1848), Idaea laevigata (Scopoli, 1763) and Eucarta virgo (Treitschke, 1835).
