  The nature conservation park, which belongs to the Spa and St. Andrew Hospital for Rheumatics of Hévíz, is 60 ha in size. The famous Lake of Hévíz, the two overfalls and the main buildings of the hospital are located in the middle of the park. They are surrounded by protective forests, parks and gravel esplanades. During the past few decades, the population of neophyton plants and invasive insects have increased considerably. These mean serious challanges to develop efficient control methods. Special care must be taken of environmental and plant protection regulations. Keeping plant protective regulations are especially strict around natural and spa waters.

  The multicoloured Asian ladybird beetle (Harmonia axyridis (Pallas, 1773)), a former successful biological control agent in the USA and Western Europe became an invasive alien species threatening the diversity of native aphidophagous insects through competition and praying, a horticultural pest consuming various fruits and adversely affecting the wine quality and a human nuisance when occurring at high densities in buildings. Due to this dubious fame, attention has been paid to it also at national level which made inevitable to find for it a fitting name in different languages. In some cases and countries a version of the English name has been chosen however, regarding the meaning of this translated term in Hungarian, the try cannot be called fortunate. The objective of this contribution is to stress the function of common animal names in the Hungarian Sprachraum and to find a right and proper alternative with the help of etymology, mythology, classical literature, art (painting) and the experiences of Hungarian fruit and grape growers.
