|Scientific Name:||Brinckiella arboricola Naskrecki & Bazelet, 2009|
|Red List Category & Criteria:||Endangered B1ab(iii) ver 3.1|

The Tree Winter Katydid (Brinckiella arboricola) is Endangered under criterion B1 because its extent of occurrence is small (~2,800 km2), it has only been recorded in three locations, and its habitat quality is estimated to be in decline. This species occurs within the Fynbos and Succulent Karoo biomes, both of which are notable biodiversity hotspots, naturally geographically restricted and under anthropogenic stress. This habitat type is predominantly utilized for livestock grazing, cultivation with annual crops, and urban development which may be detrimental to the host plants of the species. The genus of this species experienced an adaptive radiation in the region, with at least 9 species known in a relatively small geographic area. This species occurs within Matjiesrivier Nature Reserve, Western Cape, and Goegap Nature Reserve, Northern Cape.
The Tree Winter Katydid is endemic to Northern and Western Cape Provinces, South Africa.
Native:South Africa (Northern Cape Province, Western Cape)

|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is endemic to the Fynbos and Succulent Karoo biomes. It probably feeds on flowers and leaves of a very narrow range of host plants and occurs primarily on low, herbaceous shrubs and, unusually for the genus, trees. This species feeds and stridulates at night but can be found basking in the daytime on sunny days during the winter and early spring, from August until October, a time when very few insects are active (Naskrecki and Bazelet 2009).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||This species is not utilized.|
|Major Threat(s):||The principal threat to this species is habitat destruction by cultivation with annual crops, over-grazing, urban development or alien species invasion. Climate change is also likely to effect the distribution of the species host plants by altering rainfall patterns and ambient temperatures.|
No specific conservation measures are in place for this species but it is known to occur within at least two protected areas, Matjiesrivier and Goegap Nature Reserves.
