Dragonfly fauna (Insecta: Odonata) of the Brijuni National Park, Croatia

The first systematic survey of the dragonfly fauna of the Brijuni National Park was carried out during the late spring and summer of 2016. A total of 13 species was recorded at two localities on the island of Veliki Brijun, 11 of them for the first time in the area. From the literature, one additional species was documented for the Park, amounting to a total of 14 Odonata species. The most common species was Sympetrum meridionale (Selys, 1841) while the rarest was Anax parthenope (Selys, 1839). Zoogeographical analysis showed the domination of the Holo-Mediterranean zoogeographical element. Four recorded species are listed in the Red book of Croatian Dragonflies, indicating the conservation value of the investigated habitats. Both of the wetland habitats surveyed, Brijuni Pond, and the saline lakes, proved to be very important habitats for the island’s Odonata. Therefore, it is essential to protect those habitats and their biota by planning and conducting restoration activities in the near future

Dragonfly fauna (Insecta: Odonata) of Papuk Nature Park, Croatia

Odonata is an amphibious insect order constituting an important link between aquatic and terrestrial habitats. Members of the group are widely used as bioindicators of freshwater habitat health. The Odonata fauna of a total of 44 freshwater habitats in the wider area of Papuk Nature Park was investigated in the spring and summer of 2017 and 2019. Twenty-three lotic and 21 lentic habitats were included in the study. We recorded 39 Odonata species, witha higher species richness (i.e. 35) documented at lentic than at lotic habitats (i.e. 16 species). Calopteryx virgo was the most widespread species in the area, while Aeshna affinis, Epitheca bimaculata, and Sympetrum meridionale were the rarest. The most frequently recorded species at lentic sites were Platycnemis pennipes, Coenagrion puella, and Ischnura elegans, while Calopteryx virgo, Onychogomphus forcipatus, and Cordulegaster bidenatata were the most common species in lotic habitats. Although we recorded numerous anthropogenic pressures in freshwater habitats in the Park, 11 recorded species are of conservation concern, which highlights the conservation value of aquatic habitats in the study area. Our results represent the first Odonata checklist of Papuk Nature Park, and as such, they are an important contribution to our knowledge of the Odonata fauna and species distribution in Croatia

Prvi podatci o fauni vretenaca ( Insecta: Odonata) područja Vugrovca

The fauna of Zagreb has been well investigated during the last two centuries, which is evident from a series of publications. Even so, only limited data on dragonfly fauna of Zagreb have been published, and there is no current checklist. During the three years period (2009-2011) we conducted a survey of the dragonfly and damselfly fauna (Insecta, Odonata) in Vugrovec village, located on the eastern slopes of Mt Medvednica. The aim of this study is to present the first data on dragonflies from the Vugrovec area and to compile the first checklist of dragonflies of Zagreb. The suborder Zygoptera is represented in Vugrovec by 4 families and 5 species, while the suborder Anisoptera is represented by 4 families and 9 species in the area. After a review of all the available literature, in conjunction with the newly collected data, a checklist of dragonflies of Zagreb was created, including 44 species, 14 of which are listed in the Red Book of Dragonflies of Croatia. This indicates a high richness in comparison to the 70 known species from Croatia.Fauna Zagreba istraživana je tijekom posljednja dva stoljeća, što je vidljivo iz brojnih objavljenih radova. Ipak, objavljeno je vrlo malo podataka o fauni vretenaca, bez popisa vrsta. U razdoblju od 2009-2011. godine istraživali smo faunu vretenaca (Odonata) na području sela Vugrovec, koje se nalazi na istočnim obroncima Medvednice. Cilj ovoga istraživanja jest predstaviti prve podatke za faunu vretenaca Vugrovca te sastaviti prvi popis vretenaca Zagreba. U Vugrovcu smo zabilježili 4 porodice i 5 vrsta podreda Zygoptera te 4 porodice i 9 vrsta unutar podreda Anisoptera. Pregledom sve dostupne literature, zajedno s novo prikupljnim podatcima, napravljen je prvi popis vretenaca grada Zagreba koji uključuje 44 vrste. Četrnaest pronađenih vrsta nalazi se u Crvenoj knjizi vretenaca Hrvatske. Tako veliki broj vrsta upućuje na bogatstvo faune vretenaca na tome području, pogotovo ako uzmemo u obzir da je na području cijele Hrvatske zabilježeno 70 vrsta vretenaca

Novi podatki o razširjenosti in razponu nadmorskih višin pojavljanja dalmatinskega rjavčka, Proterebia afra dalmata (Godart, [1824]) (Lepidoptera: Satyrinae) na Hrvaškem

During the survey of butterfly fauna of Dalmatian mountains in the last years, Proterebia afra dalmata (Godart, 1824) was found on several new sites, including the first records of this subspecies at higher altitudes (Poštak, Svilaja, Promina, Kamešnica and Dinara Mts.). In this paper we present a much more complete picture of the distribution of this presumably rare butterfly and discuss its altitudinal distribution. The species was found at altitude of almost 1500 m, therefore the characterization of the subspecies as a lowland butterfly can be dismissed.Med raziskavami favne metuljev dalmatinskih hribov v zadnjih letih smo vrsto Proterebia afra dalmata (Godart, 1824) našli na več novih lokalitetah, vključno s prvimi najdbami te podvrste na višjih nadmorskih višinah (gore Poštak, Svilaja, Promina, Kamešnica in Dinara). V članku predstavljamo veliko popolnejšo sliko razširjenosti tega domnevno redkega metulja in razpravljamo o njegovi višinski razširjenosti. Vrsto smo našli na skoraj 1500 m višine, zat omoramo zavreči opredelitev vrste kot nižinske

Rijeka Zrmanja – žarište bioraznolikost i faune vretenaca dinarskog krša u Hrvatskoj

The Zrmanja is one of the largest rivers in Dalmatia, along with the rivers Krka and Cetina. At the same time it is one of the least surveyed larger rivers in the region, with only a few published records about its dragonfly fauna so far. Between 1984 and 2010 the authors collected data about the dragonflies around the river Zrmanja and its surroundings. Altogether 29 species were recorded at 17 localities. Of those, 12 species were recorded for the first time for the region. The most valuable record is that of Coenagrion ornatum, a local and rare Natura 2000 species. With the overview of the data from museum collections, private field data, published data and data collected during this survey the number of species known from the Zrmanja river increases to 31, making this river one of the best studied areas in Croatia. However, this is probably not the final number of species and new records are to be expected with further research.Uz Krku i Cetinu, Zrmanja je jedna od najvećih rijeka Dalmacije. Unatoč tome, fauna vretenaca rijeke Zrmanje prilično je neistražena, sa svega nekoliko publiciranih podataka o fauni vretenaca do sada. U periodu od 1984. do 2010. autori su prikupljali podatke o fauni vretenaca rijeke Zrmanje i njezine okolice. Ukupno je zabilježeno 29 vrsta na 17 lokaliteta, od čega je 12 vrsta po prvi put zabilježeno u okolici rijeke Zrmanje. Najznačajniji je nalaz rijetke i lokalne Natura 2000 vrste Coenagrion ornatum. Pregledom muzejskih zbirki, privatnih i publiciranih podataka te podataka prikupljenih ovim istraživanjem, broj vrsta za rijeku Zrmanju i njezinu okolicu porastao je na 31, čime je postala jednom od najbolje istraženih rijeka. Međutim navedeni broj vrsta najvjerojatnije nije konačan te se daljnjim istraživanjima očekuje njihov porast

Fauna danjih leptira (Hesperoidea & Papilionoidea) ruralnog dijela grada Zagreba, Hrvatska

Entomologists have researched into the butterflies of Zagreb City with different levels of intensity since the beginning of the 20th century and recorded a great number of species. Many butterfly sites historically surveyed are now completely changed or have completely disappeared due to the expansion 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 nowadays urbanized. A total of 88 butterfly species were identified, which account for 45% of Croatian butterfly fauna. Ten recorded species are threatened and listed in the Red data list of Croatian Butterflies: 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).Entomolozi su još od početka 20. stoljeća više ili manje sustavno istraživali faunu danjih leptira Zagreba i zabilježili velik broj vrsta. Nažalost, veliki broj lokacija na kojima su leptiri tada sakupljani danas su vrlo izmijenjene ili čak i nestale zbog širenja grada te drugačijeg 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 trenutno ruralno područje, no grad mu se ubrzano približava i vjerojatno je da će u bližoj budućnosti postati sastavni dio grada Zagreba. S obzirom na to faunu danjih leptira Vugrovca možemo smatrati sličnom fauni povijesno istraživanih područja koja su danas urbanizirana i dio su grada Zagreba. Utvrđena je prisutnost 88 vrsta danjih leptira, odnosno 45% faune 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)
