and its head is ochre. Until now, it has been known only from Slovakia (KARSHOLT & RAZOWSKI 1996). The caterpillar feeds on a sack cut from the underside of the leaves of hedge maple (Acer campestre) (Z. TOKÁR, personal communication). Many young hedge maples are found around the light trap that captured the moths. Further specimens were found in 2005: 6.VI. (1), 15.VI. (6), 16.VI. (1), 18.VI. (4). Its proposed Hungarian name: szlovák virágmoly. On encouragement of ANDRÁS MÉSZÁROS, staff member of the Balaton-felvidék Nemzeti Park (= National Park of Balaton Highland) on 18th March, 2004 I set up a small light trap installed with a 125 W mercury-vapour bulb at the edge of Barta-rét at Pécsely. By June the trap collected an unexpected number of moths. In every two or three weeks I complemented the material with personal collectings. At 50 metres from the light trap, an area of a few square metres was scythed in a marshy meadow scattered with great burnet (Sanguisorba officinalis), and a wooden pallet was placed there to produce some dry surface for the collecting sheet. In the night of 19th July, 2004 about 120 species came to the light, and the first species to appear was Acleris shepherdana (STEPHENS, 1852) Later, about 50 rusty yellow specimens of another species of Acleris with much smaller wingspan arrived. The light trap also captured this species until 5th August. With the help of the book by RAZOWSKI (2001) I determined them as Acleris aspersana HÜBNER, 1817. It is to be inserted before Acleris shepherdana in the Hungarian check list (SZABÓKY et al. 2002: 71). Its proposed Hungarian name: vérfű-sodrómoly. Considerable sexual dimorphism is apparent of this species, not only in the colour pattern but also in the wingspan - unusually for Lepidoptera, the females are smaller. Males (Fig. 1) have reddish brown spots on bright yellow ground and their wingspan is 15-16 mm. Females (Fig. 2) are bright rusty and their wingspan is uniformly 13 mm. According to the literature, its food plants are Potentilla erecta, Alchemilla vulgaris, Malus sylvestris, Rubus, Filipendula, Helianthemum, Sanguisorba minor, etc. Caterpillars feed in May and June, and the adults are on the wing in July and August. Probably both eggs and adults overwinter. Widely distributed in the Palaearctic, it has been known from all countries of Central Europe, except Hungary (KARSHOLT & RAZOWSKI 1996). When I showed the specimens from Pécsely to FERENC BUSCHMANN, it turned out that his collection also contained this species mingled with specimens of Acleris ferrugana [(DENIS et SCHIFFERMÜLLER], 1775), because a few years ago I deemed them the second generation of the latter species - at that time the book on Tortricidae by RAZOWSKI (2003) had still been unavailable. Data of the specimens: Bakonybél: Som-hegy, 14. VIII. 1999 (1), 12. VII. 2004 (1), ERTI light trap; Bakonykúti, 26. VII. 2003, light trap, leg GÁBOR RÁCZ;
