Erannis defoliaria (Clerck, 1759), Geometridae, mottled umber moth
E. defoliaria is present in Europe, the East Palearctic and the Near East (Fauna Europaea, http://www.faunaeur.org/).
Male wingspan is 30 to 40 mm. Females are wingless. Adults are active from October to December. The moth overwinters in egg stadium (Csóka 1995; Polak 2009). Caterpillars feed on a wide range of shrubs and trees: Salix, Betula, Quercus, Prunus, Crataegus, Alnus, Corylus, Malus, Rubus, Carpinus, Tilia, Lonicera, Sorbus, Ribes, Rosa (Moths and Butterflies of Europe and North Africa, www.leps.it) (Figures 14, 15, 16). C. australis is a new host for this species. It is a major contributor to the species-rich spring defoliator assemblages of broadleaved forests (Zúbrik et al. 2013).
Caloptilia fidella (Reutti, 1853) Gracillariidae
The species is present in Austria, Croatia, the Czech Republic, the Danish mainland, the French mainland, Germany, Hungary, the Italian mainland, Macedonia, Moldova, Poland, the Portuguese mainland, Romania, Russia, Slovakia, Slovenia, Switzerland, the Netherlands, Ukraine, Near East and Asian Turkey (Fauna Europaea, http://www.faunaeur.org/; Lesar and Govedič 2010). The species was found in Sečovlje (Slovenia), on October 22, 1977 on the leaves of Humulus lupulus (Maček 1999). C. australis is a new host record for this species (Figure 17). They mine the leaves of their host plants.
Neoclytus acuminatus (Fabricius, 1775), Cerambycidae, redheaded ash borer
A native Nearctic species, N. acuminatus was introduced to northeastern Italy from North America in the wood of North American ash. It eventually expanded into the western Balkans, central and northern Italy, and Switzerland (Brelih et al. 2006). It is present in Croatia, Hungary and Slovenia. It is currently quite common in the southwestern part of Slovenia, which is where Schmidt found it in the mid-19th century (Brelih et al. 2006). It is present in Slovenian Istra, Primorska and Notranjsko (Brelih et al. 2006). Well-known Croatian coleopterologist Petar Novak mentions N. acuminatus from the area of Zadar in June 1891 (Hrašovec 2009). There are also quite important research outcomes in the field of semiochemical communication, also related to the redheaded ash borer: the existence of an aggregation pheromone produced by males of N. acuminatus has recently been proved as being the first known pheromone amid cerambycids as a group (Hrašovec 2009). It is extremely polyphagous in deciduous trees (Carpinus, Betula, Corylus, Ostrya, Quercus, Fagus, Castanea, Juglans, Salix, Populus, Ficus, Morus, Ulmus, Prunus, Pyrus, Rosa,
