This species appears always to have been rare and was last seen in 1977 (Pinhey 1979). Despite very intensive searches between 1993–2000, the species has not been rediscovered, while it habitat has been greatly modified. Further searches are planned in 2004. Meanwhile, the species is currently assessed as Data Deficient.

Orthetrum rubens
Formerly, this species was recorded from various localities in the Western Cape, including Table Mountain. Clearly it was never an abundant species (Pinhey 1979, 1984). A great deal of searching time was devoted to this species between 1993 and 2000 but it was never rediscovered,.
It seems to be extinct afterall, many had hoped that searhes would found it as most of the range is in a nationalpark.

Range and Population Formerly, this species was recorded from various localities in the Western Cape, including Table Mountain. Clearly it was never an abundant species (Pinhey 1979, 1984). A great deal of searching time was devoted to this species between 1993 and 2000 but it was never rediscovered, suggesting that it may be under severe threat. Thought to be fewer than 500 mature individuals left. Habitat and Ecology High, montane streams and kloofs. Threats It is not clear why this species has not been rediscovered as its upland habitat is largely in protected areas. However, it may breed at lower elevations where threats are from plantation forestry, alien invasive trees, alien trout and, in Du Toit’s Kloof, from fish farming. Conservation Measures Searches must continue, especially for the larval habitat. Continued removal of alien trees must also continue. Trout should no longer be released and those present should be removed. www.redlist.org/search/details.php?species=15543 |

Formerly, this species was recorded from various localities in the Western Cape, including Table Mountain. Clearly it was never an abundant species (Pinhey 1979, 1984b). A great deal of searching time was devoted to this species between 1993 and 2006 but it was never rediscovered, suggesting that it may be under severe threat. There is no information available at all on current population size or trends. It has not been seen since 1977. Habitat and Ecology: High, montane streams and kloofs. However, specific habitat is not known - it may be a montane specialist, in which case it may not be particularly threatened; or it may be a lower elevation species, in which case it may be seriously threatened. More data are needed. Threats: It is not clear why this species has not been rediscovered as its upland habitat is largely in protected areas. However, it may breed at lower elevations where threats are from plantation forestry, alien invasive trees, alien trout and, in Du Toit’s Kloof, from fish farming. Conservation Measures: Searches must continue, especially for the larval habitat. Continued removal of alien trees must also continue.

According to Tarboton & Tarboton (2015) this species was recently rediscovered at Jonkershoek in open uplands at 1100-1300m. There is photographs of both male and female taken at Jonkershoek.
