Calling signals. Signals of males from the following localities were investigated.

1. Crimea, environs of Pereval’noe Village halfway from Simferopol to Alushta, from Salix alba, 16–17. VI. 1997, calling signals of 3 males recorded at 22–25 oC.

2. Southeastern European Russia, Saratov Oblast, 15 km southwest of Khvalynsk Town, environs of Ulyanino Village, from S. alba and S. euxina, 15–17. VI. 1996, signals of 5 males recorded at 22 and 31 oC.

3. Southeastern European Russia, Volgograd Oblast, Ilovlya River about 5–7 km from the mouth (ca. 4 km southwest from Ilovlya Town), from S. alba. 8. VI. 1996, calling signals of 3 males recorded at 20–26 oC.
