Isophya stysi - Stys' Plump Bush-cricket
Cejchan, 1958

Description: Ground colour green, body length 20-28 mm, ovipositor 10-11 mm. Male's subgenital plate is short, narrow, notched at the end.
Similar species: the other Isophya species
Adults: from June to August
Song:
The song is very similar to that of I. modestior , but the vibrations at the beginning of the syllables are slower, resulting in a scratchy, raspy sound. The interval between the syllables is 1 to 2 minutes.
Habitat:  Forest clearings and edges, tall vegetation by streams.
Distribution:
An endemism of the Eastern Carpathians, this species has isolated and small populations in the eastern part of the country (Zempléni Mts., Aggteleki-karszt, Beregi-sík, Körös-vidék).
Note: Strictly protected species.
