The Nearctic leafminer of black walnut Coptodisca juglandiella (Chambers, 1874) was found in Hungary and reported as new for Europe. Larvae were found in leafmines on black walnut (Juglans nigra (L.)), white walnut (J. cinerea (L.)) and Arizona walnut (J. major (Torr.)); the latter two Juglans species are new host plant records for C. juglandiella. Mines of Coptodisca lucifluella (Clemens, 1860), another Nearctic invader, were found on leaves of bittemut hickory (Carya codiformis (Wangenh.) K.Koch) and Caucasian wingnut (Pterocarya fraxinifolia (Lam). Spach.) (a new hostplant record), in addition to common walnut (Juglans regia L.). Interestingly, C. lucifluella is thought to have performed a host plant shift after its introduction into Europe, whereas C. juglandiella apparently did not. Coptodisca juglandiella has three generations in Hungary. The autumn generations of both species produced many more mines than the spring generations. One hymenopteran parasitoid specimen was reared from C. juglandiella. Larvae, mines and adults of C. juglandiella and C. juglandiella can be easily distinguished, differences are presented and illustrated. The genitalia of C. juglandiella are described for the first time.

Currently, more than 1540 species of Coleophoridae are known in the world (Baldizzone, unpublished data). Of this total, about 600 are found in Europe, where this family of Lepidoptera has always attracted the attention of researchers owing in particular to its larval cycle, which normally occurs in a mobile case. However, even though the European Coleophora fauna is remarkably well known compared to that of other continents, many species still remain to be described on the basis of material already preserved in museums and private collections. It is expected that others will be discovered with an increase in research, in particular with breeding, a practice that often makes it possible to find species that are rarely encountered in nature, both through direct harvesting and with the use of lamps and light traps.

The fig leafhopper, Ficocyba ficaria (Horváth, 1897) (Cicadellidae: Typhlocybinae: Typhlocybini) was described from the coast of the Adriatic sea. Since then the species has been reported from several countries, primarily from the Mediterranean area of the Western Palaearctic Region. In the course of the current study the species was found at several locations in Hungary, indicating the presence of stable populations. An overview of currently known distribution of the species is provided. Recent records of the species including results of the present study indicate range expansion of the fig leafhopper.

During the past years, we found a new Coleophora taxon in Hungary that proved to be unknown for the fauna of the country. We identified the unknown specimens using combined information from morphological examination including the female genitalia and genetic analyses. We sequenced the Cytochrome Oxidase “COI” gene of the mitochondrial DNA, and used the resultant base-pair sequence for species identification, using the BOLD platform, and for preparing a phylogenetic tree with the most closely related taxa involved. Our results show that larval and adult morphology, genitalia structure, and the sequence of the COI region of the unknown specimens are most similar to those of Coleophora gazella Toll, 1952. The habitats of the species in Hungary are strongly isolated from the nearest population in Turkey (Anatolia). We also studied habitat characteristics and life history of the species, which are briefly presented in this paper. The article contains four figures and two tables.

We describe Coleophora cytisicolella sp. nov . (Lepidoptera: Coleophoridae), a new species from material collected in Austria and Hungary during recent fieldwork. The collected specimens were found only in these countries within the Pannonian Biogeographical Region, and were exclusively associated with Chamaecytisus austriacus (L.) Link (Fabaceae). The taxonomic status of the new species was determined by applying traditional macro- and micromorphological methods and genetic analysis, including genitalia examinations and DNA barcoding (cytochrome c oxidase subunit I). In addition to the results of morphological comparisons and genetic analysis, we present further information on the habitat, life history, and larval food plant of this species. Our results revealed that the examined individuals belong to a species new to science, which is a member of the Coleophora genistae Stainton, 1857 species group, and described here as C. cytisicolella sp. nov . Based on the molecular results, the closest relative of the new taxon is Coleophora bruttia , a species described from southern Italy. Although the examined barcoding sequence poorly differentiated these taxa, the micromorphological features of the genitalia revealed their separate status.

Cydia interscindana (Möschler, 1866) has spread through several European countries in the past few years, becoming an invasive pest of ornamental trees. It was collected in Hungary for the first time in a pheromone trap set for Cydia pomonella (Linnaeus, 1758) in 2014. Here we discuss its recent distribution in Hungary based on intensive sampling between 2018 and 2020, which showed the dispersal of the pest by humans. Two formerly unknown host plants are also recorded. The damage caused by the larvae, the external morphology of the adult male, larva, pupa (described for the first time) and pupal exuviae are presented. We also analyse DNA barcodes, identifying this pest for the first time via DNA sequencing of immature stages. Introduction Cydia interscindana is native in the Mediterranean region, where it was described by Möschler in 1866 from Andalusia. It is distributed in Mediterranean countries including Portugal (Corley 2004), Spain (Férriz et al. 2006), France (Lévêque et al. 2017) and Italy (Minelli 1995). Later the species was recorded in the British Isles (Knill-Jones 2020), Belgium (De Prins 2016), Switzerland (Swisslepteam 2010), Slovakia (Pastorális et al. 2018) and Russia (Caucasus; Schurov et al. 2017). In Hungary, Cydia interscindana adults were caught by a sticky delta pheromone trap (CSALOMON RAG type) for Cydia pomonella (Linnaeus 1758) in 2014 during a study on swarming dynamics of the latter pest in Budapest. This provided the first record of the species in the Carpathian basin (Szabóky 2014; Takács and Szabóky 2015). In the Mediterranean region larvae feed on Juniperus oxycedrus (L.) (Miller 1990). In Belgium the larva was recorded on Juniperus spp. (Meert et al. 2019). J. oxycedrus is not native in Hungary, but Cupressus × leylandii A.B. Jacks. & Dallim 1926, Platycladus orientalis (L.) Franco 1949 and Chamaecyparis lawsoniana (A. Murray bis) Parl. 1864 are popular evergreens used as ornamental trees both in parks and gardens. In Hungary several pests of these plants have been recorded, all probably introduced with imported plants; in the literature, 11 Lepidoptera, nine Coleoptera and six Hemiptera species have been mentioned already (Csóka and Kovács 1999; Maráczi 2013; Bozsik et al. 2016; Schurov et al. 2017). However, until the end of the 2000s, only Scolytidae (Coleoptera) species caused serious damage (Bozsik and Szőcs 2017). In 2012, an outbreak of the formerly detected (Muskovits 2001) Lamprodila festiva (Linnaeus 1767) (Buprestidae) took place in Budapest (Németh 2012) causing serious damage on Platycladus orientalis and several ornamental gymnosperm species. This outbreak was certainly caused by introduced specimens, that had arrived with trees from the Mediterranean region where this beetle is a well-known pest (Merkl 2016), whose abundance in Hungary increases due to climatic change (Csóka et al. 2018). Based on the available data, in Hungary this beetle pest has also been blamed for all the damage caused on Cupressus, Platycladus and Chamaecyparis trees and management has been carried out only against them. In 2018, a larva of L. festiva, an unidentified caterpillar and a freshly emerged specimen of Cydia interscindana were collected simultaneously from a Leyland cypress in Székesfehérvár (Central Hungary). In that year, similar Lepidoptera larvae were found in three neighbouring villages: Velence, Sukoró and Pákozd. To identify the sampled caterpillar, DNA analysis was undertaken. Additionally, in 2019–2020 a country-wide investigation was carried out to map the distribution and abundance of C. interscindana and gather data on bionomics of this pest in the Carpathian basin.
