Isophya rizeensis Sevgili, 2003 (Orthoptera: Tettigoniidae: Phaneropterinae) is endemic to the Firtina Valley in the northeast of Turkey. This paper describes the spatial distribution and habitat characteristics of nymphs and adults off rizeensis within the Firtina Valley taking color variation into consideration. Both male and female color morphs showed marked differences in spatial distribution with dark morphs appearing in the lowlands (between 300-1000 m) and light morphs appearing in the highlands (between 1000-2000 m). Both development stages (nymphs and adults) were found only in forb/herb and shrub vegetation within certain open habitat patches along the Firtina Valley. Microclimatic and vegetative properties of different habitat patches and behavioral differences oft rizeensis in these different patches were also evaluated. Factors responsible for the differential distribution of color morphs were discussed in relation to characteristics of local habitat patches.
