The presence of more than ten new species forCroatia has been recently confirmed; Colias erate (Esper, 1804) (LORKOVI] et al., 1992)Leptidea reali (Lorkovi}, 1993), Zerynthia cerisy (Godart, 1824) (SALA & BOLLINO, 1994),Coenonympha oedippus (Fabricius, 1787) (KU^INI] et al., 1999), Lycaena ottomanus (Le-fèbvre, 1830) (MIHOCI et al., 2005), Polyommatus damon (Denis & Schiffermüller, 1775)(MIHOCI et al., 2006), Danaus chrysippus (Linnaeus, 1758) (PERKOVI], 2006), MaculineaNAT. CROAT. VOL. 19 No 1 239–244 ZAGREB June 30, 2010Croatian Natural History Museum, Demetrova 1, Zagreb, Croatiaalcon (Denis & Schiffermüller, 1775) (MIHOCI et al., 2007), Cacyreus marshalli Butler,1898 (KOSMA^ & VEROVNIK, 2009) and Lasiommata petropolitana (Fabricius, 1787) (MI-HOCI & [A[I], 2009). Nevertheless, the butterfly fauna of Croatia is still far fromwell explored.According to KARSHOLT & RAZOWSKI (1996) the Nymphalidae family in Europecounts altogether 217 species. In Croatia, only 85 species are present, including thelatest finding of Lasiommata petropolitana (MIHOCI & [A[I], 2009).The Brenthis genus is represented in Europe by three species: Brenthis daphne(Denis & Schiffermüller, 1775), Brenthis hecate (Denis & Schiffermüller, 1775) andBrenthis ino (Rottemburg, 1775), and all of them are present in the Croatian fauna.While B. daphne and B. hecate are quite common, B. ino is considered a rare speciesin Croatia according to MIHOCI & [A[I] (2005).The Lesser Marbled Fritillary (B. ino) is a univolent species which flies in centraland south Europe in June and early July. Eggs are laid singly primarily on Filipen-dula ulmaria, F. petalana, Rubus chamaemorus, R. idaeus and Sanguisorba officinalis. Itcan be usually found in damp forest places, close to bushes of light woodland, nearrivers and marshes. Its larvae feed on flowers and leaves. It hibernates as an ovumor small larva (TOLMAN & LEWINGTON, 2008).MATERIAL AND METHODSButterflies were collected by an entomological net in Vugrovec (X: 5586762, Y:5081473), close to Zagreb on July 5th, 2009. All specimens are placed in a privatebutterfly collection (Koren – Ladavac) in Pazin.Taxonomic determination of the collected butterflies was done according to TOL-MAN & LEWINGTON (2008). The butterfly nomenclature was done according to thenew European red list of butterflies: http://cmsdata.iucn.org/downloads/euro-pean_red_list_butterflies_new.pdf. The positions and coordinates at which the but-terflies were caught were determined using Garmin e-Trex Vista GPS device.RESULTS AND DISCUSSIONOnly seven previous findings for B. ino in Croatia are known; Josipdol (MANN,1867; ABAFI-AIGNER et al., 1896), Plitvi~ki Ljeskovac (KO^A, 1901; LORKOVI], 2009),@umberak Mountain – Sveta Gera & Slapnica (JAK[I], 1988; BOJANI], 2001), ^edanj(Kupa River valley) (MLADINOV, 1980), Velebit Nature Park – Sun|erac, (MIHOCI &[A[I], 2005) and Karlovac ([PANI], 2009) (Fig. 2).Zagreb and the surrounding area were studied from the beginning of the 20thcentury by a great number of authors (VUKOTINOVI], 1879; GRUND, 1908, 1916; GUSSICH,1917; LORKOVI], 1997) so it was difficult to expect any new finding of species aroundZagreb. But during research into butterflies at different localities on the easternslopes of Medvednica in spring and summer of 2009, one specimen of B. ino wasobserved and collected. Apart from B. ino, at the same locality we also found B.daphne and B. hecate (Fig. 1). B. daphne was by far the commonest species with morethan 10 observed specimens, followed by B. hecate with 6 specimens. The B. ino240 Koren, T. & Zadravec, M.: First record of Brenthis ino around Zagreb, Croatiaspecimen was found near the forest edge of a wet meadow, close to the main roadthat leads to Vugrovec (Fig. 3). The meadow is surrounded by a forest and a smallstream and was once agricultural land, according to the local inhabitants. Althoughmuch effort was devoted to finding B. ino in nearby meadows and localities (Bede-nik, Kr~), no other specimens were found.Nat. Croat. Vol. 19(1), 2010 241Fig. 1.

The closest known site of B.ino is in @umberak Mountain (JAK[I], 1988; BOJANI], 2001) around 70 km away.That shows that the distribution of B. ino in Croatia is still far from well known andfurther efforts will be needed to establish a more accurate distribution of this spe-cies in Croatia.As only a single specimen of this species was observed at that site, additionalvisits will be required, possibly at earlier dates in June. Since the species has recentrecords only from four sites, these should also be re-checked to evaluate possiblethreats and the risk of local extinctions.Received September 15, 2009REFERENCESABAFI-AIGNER, L., PAVEL, J. & UHRYK, F., 1896: Fauna Regni Hungariae.

Koren & M. ZadravecTijekom istra`ivanja faune dnevnih leptira isto~ne padine Medvednice, u Vugrov-cu u okolici Zagreba, nai{li smo na jednu jedinku leptira Brenthis ino (Rottemburg,1775). Ovaj je nalaz zanimljiv zbog toga {to je ova vrsta u Hrvatskoj do sadazabilje`ena na samo sedam lokacija; Josipdol (MANN, 1867; ABAFI-AIGNER et al., 1896),Plitvi~ki Ljeskovac (KO^A, 1901, LORKOVI], 2009), @umbera~ka gora – Sveta Gera &Slapnica (JAK[I], 1988; BOJANI], 2001), ^edanj (dolina Kupe) (MLADINOV, 1980), ParkPrirode Velebit – Sun|erac, (MIHOCI & [A[I], 2005); Karlovac ([PANI], 2009), a nalazu Vugrovcu je najsjeveroisto~niji nalaz do sada (Fig. 2). Dodatnu va`nost ovomenalazu daje to {to se istra`ivani lokalitet, Vugrovec, nalazi u neposrednoj blizinigrada Zagreba, ~ija je fauna leptira ve} dulje vrijeme vrlo dobro poznata i istra`ena(VUKOTINOVI], 1879; GRUND, 1908, 1916; GUSSICH, 1917; LORKOVI], 1997). Unato~ tomeova vrsta u Zagrebu nije do sada nikada potvr|ena. Na istom lokalitetu na|ene su ipreostale dvije vrste roda Brenthis, B. daphne i B. hecate (Fig. 1), i to u znatno ve}ojbrojnosti nego B. ino. Daljnjim istra`ivanjem okolnih i udaljenih lokaliteta (poputKr~a i Bedenika) nije prona|ena niti jedna jedinka vrste B. ino. To ukazuje da je ovavrsta rijetka ~ak i na lokalitetu u Vugrovcu. Budu}a istra`ivanja trebala bi bitiusmjerena na daljnje istra`ivanje okolice Zagreba u svrhu utvr|ivanja prisutnostiove vrste i na nekim drugim lokacijama.
