With nearly 60 described forms Uromenus is the most species-rich genus of the tribe Ephippigerini, a west Palearctic group of flightless bush-crickets (katydids). As it is typical for bush-crickets, Uromenus males produce species-specific calling songs to attract females prepared to mate. These insects are relatively large and their songs have alwa...

Dr. Barnabás Nagy (1921–2020), a naturalist, orthopterologist, agrozoologist and forward-looking ecologist covered a rich scientific career. In commemoration of his significant contribution to entomology, we attempt to shed some light on a selection of his achievements. While devoted to his chosen insect order, Orthoptera, he was sensitive also to...

Grasshoppers and crickets of Montenegro have never been systematically studied. In this paper we present new distribution records of 119 Orthoptera species from Montenegro, sampled at 116 localities in different parts of the country in the period between 2010 and 2017. We also present records of older material deposited in the collection of the Hun...

During his long active life Barnabás Nagy (1921–2020) worked on two main fields of science: agricultural entomology and orthopterology. Here we present a full list of his publications, arranged into the following topics (with the actual numbers of the publications): scientific papers including books, book chapters and journal articles (241), scient...

The first annotated checklist of crickets and grasshoppers (Orthoptera) of Croatia is presented.

The insect fauna of the Dinarides is not widely studied. In 2013 and 2014, an orthopterological survey wasconducted on the Poštak Mountain and its surroundings in the Lika region (Croatia), in order to sample the orthopterancommunities of the prominent habitat types of the area. From 24 sampling sites, 80 Orthoptera species (44 Ensifera and 36Caeli...

Bosnia and Herzegovina is among the orthopterologically well studied countries in the Balkans. Research on the grasshopper fauna started in the 19th century and became the most intensive during the work of Sonja Mikšić (1926–1987). It is therefore surprising that our collecting activity between 2013 and 2017 and a visit in the National Museum of Bo...

A Duna-Tisza köze északnyugati részén húzódó Turjánvidék változatos fátlan élőhelyei gazdag egyenesszárnyú-faunának adnak otthont.

Genus Isophya is one of the most species-rich genera from the European Orthoptera, comprising 97 taxons described so far, commonly known as plump bushcrickets. Based on their morphology, most of these taxa are grouped in several species complexes. One of these is “Isophya pyrenaea” species complex with 14 species, some of them recently described (W...

A new, morphologically cryptic species of phaneropterine bush-crickets is described from the grasslands of the Romanian Eastern Carpathians. Despite the morphological and acoustic similarities with the recently described Isophya nagyi Szövényi, Puskás & Orci, I. bucovinensis sp. n. is characterized by a peculiar male calling song, with faster sylla...

Widespread amongst orthopterans, acoustic communication plays an important role in the mate recognition system of these insects. Within the Isophya camptoxypha group, three distinct subgroups have been identified: species with simple acoustic repertoires, consisting of a repetitive single syllable type (e.g. I. camptoxypha (Fieber)), species produc...

The conspicuous colors found in many lizards transfer information about their owner’s characteristics that are relevant to mating and social systems. Female European Green Lizards (Lacerta viridis) have been shown to prefer males with high ultraviolet (UV) throat reflectance. Additionally, components of throat patch color (such as UV chroma and bri...
