Anaceratagallia fragariae

Biology. In Moscow Oblast was collected on dry meadow with sparse xerophytic vegetation; in the laboratory, one male lived for several days and produced signals on Rumex acetosella. In Southern Kazakhstan it was abundant on polydominant meadows in the foothills of Zailiysky Alatau Mtn. Range. In southeastern Kazakhstan it was found on a rather mesophytic meadow on the riverbank. Calling signal. Signals of males from the following localities were investigated. 1. Moscow Oblast, Voskresensk Region, dry meadow with xerophytic vegetation on the Western edge of Beloozerskiy Town, on Rumex acetosella, 1. VII. 2018, signals of one male recorded at 27 oC. 2. Southeastern Kazakhstan near the Eastern Balkhash Lake, meadow on the bank of the Lepsy River ca. 1 km upstream from the Lepsy Town, 27. VI. 2019, signals of one male recorded at 33 oC. Calling signal is a complex phrase lasting for 10 – 20 s (Figs. 194 – 198). It begins with a succession of pulses or syllables variable both in shape and repetition period. Immediately afterward is a short (ca. 1.5 – 3 s) succession of more uniform syllables following each other at a rate of about 13 – 16 / s in our recordings. After a pause lasting from 1.5 – 2 up to 5 – 10 s one more such succession follows. Signals of males from Moscow Oblast (Figs. 194 – 195, 197) and Kazakhstan (Figs. 196, 198) have no significant differences.
