Data to knowledge of Hungary Pterophoridae Fauna, No. 11. The Crombrugghia species of Hungary (Lepidoptera: Pterophoridae).

Author presents serially the results of the revision of Pterophoridae fauna inHungary. Data are reported on the geographical distribution of Crombrugghia Tutt, 1906 species inHungary. Structure of genitalia and morphological characteristics of wings are illustrated by figures.Crombrugghia tristis (Zeller, 1841) is in general a smaller species and has a more brown-grey colourthan the red-brown C. distans (Zeller, 1847). While the genera Crombrugghia is easily identified,species determinations are more challenging, often requiring dissection and preparation of genitaliaslides. He analysed the habitats and the Hungarian distribution of the species, which is shown onUTM-grid and European maps. Crombrugghia moths are declining seriously in most regionsHungary. Moths are disappearing from Hungary's grasslands at an alarming rate. The drasticdecline of moths Hungary is due to a loss of grassland habitats as permanent pasture is ploughed upto plant intensively managed crops. Action is needed urgently at a Hungarian level to halt theirdecline and restore a countryside rich in moths. With 12 figures.
