Behaviour

The male calling song is similar in general pattern to that of I. pyrenaea, but the main part of each syllable is much longer, about 250-330 ms, and the syllables are repated more rapidly, about 2/s. 'After-ricks' are also usually present, following the main part of the syllable after an interval of about 70-130 ms.

Behaviour

This subspecies was recently described from NE Romania and differs from the nominal form (Central Europe) mainly in acoustics and less in morphology. Males from the Moldavian populations sing shorter syllables, formed of 30-58 impulses and lasting for about 89-200 ms, while males of the nominal subspecies produce longer syllables, formed of 80-125 impulses and lasting for about 250-443 ms. The stridulatory le is shorter (195-229 pegs) in I. kraussii moldavica, compared with 260-305 pegs in I. kraussii kraussii (Iorgu & Heller, 2013).
