The Southern Oak Bush-cricket is the most recent addition to the Netherlands Orthoptera fauna. It is known from Maastricht, Culemborg and the towns around the city of Rotterdam. The insects were mainly found on walls of large buildings during late autumn. Some of the specimens were first mistaken for nymphs of the Oak Bush-cricket. The discovery of the isolated populations near Rotterdam supports the hypothesis that the expansion in Northwestern Europe is due to transport by cars. Its reduced wings are not suitable for flight.
