1. To persist in a highly fragmented environment, such as the intensively used agricultural landscapes of Europe, species may need to successfully disperse between sub-populations. This paper describes a capture – mark – resight experiment to investigate movement and dispersal patterns of the flightless bush cricket species Pholidoptera griseoaptera. 2. Movement parameters showed little difference between juveniles and imagos as well as between males and females. Both developmental stages and sexes moved considerable distances, were cap\able of crossing habitat boundaries, and showed successful inter-patch dispersal through the agricultural matrix. 3. The results suggest that P. griseoaptera exhibits movement behaviours that compensate for its inability to fly. It was concluded that the good dispersal ability exhibited by animals of both sexes and developmental stage is an important factor allowing P. griseoaptera to persist in fragmented agricultural landscapes.
