Insects - Insecta As the Dragonflies (Odonata) are closely associated with water, the pollution of water bodies strongly affect their populations and reduce their numbers. Several dragonflies living here are Mediterranean species, such as the protected Anax parthenope, and Stylurus flavipes. The latter species disappeared from the River Berettyó as a consequence of water pollution. The ground beetles (Carabus) are common, and as their name suggests they are dwelling mainly on the soil surface, and they move quickly. The predatory species are useful and hence protected like the Forest caterpillar-hunter (Calosoma sycophanta) and Carabus cancellatus. The predatory ground beetles are the main consumers of caterpillars, which destroy the foliage of trees. The stag beetle (Lucanus cervus) is the largest beetle species of Hungary, its eggs are deposited among the roots of decaying oak logs. Among the Longhorns (Cerambicidae), the Pontomediterranean Cortodera flavimana is restricted to the MedgyesegyházaKétegyháza-Elek-Gyulavári-Tarhos-Bélmegyer stripe in Hungary. The order of Butterflies (Lepidoptera) is probably the most beautiful and most species-rich group of insects. The occurrence of species is usually related to, and hence restricted by the presence or absence of a single host plant species. The number of protected species is under one hundred. The number of lepidoptera species in the Southern Trans Tisza region is approximately 500. The most common is the Large garden white (Pieris brassicae), the largest is the protected Large emperor moth (Saturnia pyri ). The genetically varied populations of Clouded black apollo (Parnassius mnemosyne) are found along the banks of the River Fekete-Körös. The Southern Festoon (Zerinthia polyxena) is a characteristic species of southern regions. (The former two species is listed as protected by the Bern Convention.)
