Entomologists have researched into the buterfies of Zagreb City with diferent levels of intensity since the beginning of the 20 th century and recorded a great number of species. Many buterfy sites historically surveyed are now completely changed or have completely disappeared due to the expan- sion of the city and changes in habitat management. Our research was conducted between March 2009 and September 2010 in the Vugrovec area, located at the northeastern edge of the city. Vugrovec is still a rural area, but the city itself is fast approaching, and will probably be merged in the near future. So this area could be considered similar to the historically studied sites in the former rural areas nowa- days urbanized. A total of 88 buterfy species were identifed, which accounted for 45% of Croatian buterfy fauna. Ten recorded species are endangered and listed in the Red data list of Croatian Buter- fies: Lycaena dispar (NT), Glaucopsyche alexis (NT), Pseudophilotes vicrama (NT), Scolitantides orion (NT), Phengaris arion (VU), Papilio machaon (NT), Pieris brassicae (DD), Polyommatus thersites (NT), Apatura ilia (NT), and Heteropterus morpheus (NT).

Vol. 22, No. 2., 253–264, 2013, Nat. Croat., Zagreb. Entomolozi su još od početka 20. stoljeća više ili manje sustavno istraživali faunu danjih leptira Zagreba i zabilježili velik broj vrsta. Nažalost, danas su mnoge lokacie na kojima su leptiri tada saku- pljani, izmienjene ili nestale zbog širenja grada te drugačieg upravljanja gradskim parkovima i zelenim površinama. Između ožujka 2009. godine i rujna 2010. godine istraživani su danji leptiri na području Vugrovca, na sjeveroistočnoj granici grada. Vugrovec je trenutačno ruralno područje, no vjerojatno će u bližoj budućnosti postati sastavni dio grada koji mu se ubrzano približava. S obzirom na to, faunu danjih leptira Vugrovca možemo smatrati sličnom fauni poviesno istraživanih područja koja su danas urbanizirana i dio su grada Zagreba. Utvrđena je prisutnost 88 vrsta danjih leptira, odnosno 45% fau- ne danjih leptira Hrvatske. Deset zabilježenih vrsta se smatra ugroženima te su navedene na Crvenom popisu danjih leptira Hrvatske: Lycaena dispar (NT), Glaucopsyche alexis (NT), Pseudophilotes vicrama (NT), Scolitantides orion (NT), Phengaris arion (VU), Papilio machaon (NT), Pieris brassicae (DD), Polyommatus thersites (NT), Apatura ilia (NT) i Heteropterus morpheus (NT).
