Seychelles Predatory Bush-Cricket
The Seychelles Predatory Bush-Cricket, Seselphisis visenda, has been assessed as Endangered on The IUCN Red List of Threatened SpeciesTM. The species is endemic to the Seychelles, where it only occurs in the cloud forests of the granitic islands Mahé and Silhouette. Individuals of this species are found on leaves of trees, particularly on palms. Recently, a sibling species, Seselphisis praslinensis has been described from Praslin.
The cloud forests of the Seychelles are severely threatened by the invasion of non-native plants, particularly cinnamon (Cinnamomum verum), jackfruit (Artocarpus heterophyllus) and soapbush (Clidemia hirta). Moreover, introduced animals, such as rats and tenrecs, are threatening the native fauna. An additional threat is climate change; recent droughts have damaged the native vegetation.
The Seychelles Predatory Bush-Cricket occurs in the Morne Seychellois National Park. However, although the area is protected by law, a strategic plan to control or eradicate invasive species is needed in order to preserve this and other endemic species. It also remains unknown how the negative impact of climate change can be mitigated.
