Ivković, Slobodan, Online, Published & Version, Final, 2017, First results of a faunistic survey on the Orthoptera of Jadovnik Mountain, southwestern Serbia, with data on the calling songs of some bush cricket species, Turkish Journal of Zoology 41 (6), pp. 1083-1095 : 1093

65. Chorthippus biguttulus (Linnaeus, 1758) : 2♂♂, Vodice (9), 18.07.2016 ; 3♂♂, Mali Jadovnik –forest roadside (18), 20.07.2016 .

ECOLOGY: Pratinicole; graminicole.

Remarks: Members of Chorthippus biguttulus group are easily recognizable by their calling song; this method was applied for their identification on the field. At locality Mali Jadovnik–forest roadside, male calling songs observed in the field were similar to the song of Chorthippus bornhalmi Harz, 1971 . As collected males did not produce song in captivity, the number of pegs, which is one of the useful morphological characters for determination of members of the C. biguttulus group ( Willemse et al., 2009), was used. Two analyzed males had 105 and 108 stridulatory pegs, which is in the upper border of the range in C. biguttulus and the lower border of the range in C. bornhalmi ( Willemse et al., 2009) . C. bornhalmi was reported for the first time in Serbia 2 years ago ( Skejo and Ivković, 2015) and so it is possible that this species is present in this part of Serbia too; additional analyses of calling songs in the future will show the real status of the species, which is found in the locality Mali Jadovnik–forest roadside.
