Isophya modesta - Modest Plump Bush-cricket
Frivaldszky, 1867

Description: One of the largest (23-27 mm) Plump Bush-cricket species in Hungary. The male's wing is slightly longer than the pronotum, with a kidney-shaped brown patch on each wing. The end of the subgenital plate is deeply notched. The ovipositor is relatively long (15-18 mm) and more strongly curved than by I. costata.
Similar species: the other Isophya species
Adults: from May to July
The very distinctive song consists of two parts: first a short solitary and powerful chirp (syllable), followed by a series of quieter syllables, like the creaking of an old door. Between the two parts is an interval of 4-8 seconds. It seldom sings, so it is difficult to detect. The frequency peak is between 10 and 20 kHz.
Habitat:  Dry grasslands, hillsides. Prefers low vegetation.
This Balkan species is known from different mountain ranges in Hungary, but always very local (e.g. Mecsek, Villányi-hg., Somló, Budapest, Mátra, Bükk).
Note: Protected species in Hungary.
