The first fossil record of a spittlebug affiliated to Aphrophora Germar, 1821 (Hemiptera: Cercopoidea: Aphrophori-dae) is reported from Bulgaria (Western Rhodopes, Satovcha Graben). The fossil from Middle Miocene deposits represents the first recorded evidence of fossil Auchenorrhyncha in Bulgaria. A forewing illustration of the new finding and rev...
Orientus ishidae (Matsumura, 1902), a leafhopper species native to East Asia, has been increasingly reported in Europe due to its potential role as a vector of phytoplasmas affecting agricultural crops. In this study, we present the first confirmed record of O. ishidae in Bulgaria, collected from Varna town during field surveys in 2024. The occurre...
Psyllids (Hemiptera: Psylloidea) are plant sap-sucking insects whose identification is often difficult for non-experts. Despite the rapid development of DNA barcoding techniques and their widespread use, only a limited number of sequences of psyllids are available in the public databases, and those that are available are often misidentified. Here,...
A new ant-attended species, Balcanocerus agapetomyrmices sp. nov. (Hemiptera: Cicadellidae: Eurymelinae), is described from Bulgaria. The only known host plant is Pyrus amygdaliformis Villars, 1807 (Rosaceae). Both the adults and the nymphs often form small aggregations of 4–6 individuals that are frequently visited by Lasius bombycina Seifert & Ga...
Agonoscena cisti (Puton, 1882) (Psylloidea, Aphalaridae) is reported for the first time from the Maltese Islands.
