Overview

Distribution

Range Description

This species is endemic to the eastern mountains of Zimbabwe and there are records from the Chimanimani Mts and the Vumba [Bvumba] Mts. It must also be found on the Mozambique side of the border, which has barely been studied as far as butterflies are concerned and which occupies a larger area than in Zimbabwe. Nothing much is known about the species, all material having been collected in traps (Pringle et al. 1994) but even the relatively localized members of the black Charaxes butterflies are usually well distributed and relatively common in their area of occupancy (AOO) and this is probably the case for this species as well. The extent of occurrence (EOO) of the known Zimbabwean distribution of this butterfly is approximately 2,000 km2, but this excludes the currently unknown Mozambique distribution which is probably larger. The AOO is smaller still, but the habitat is primarily miombo woodland in the eastern highlands which is fairly extensive within the EOO (Nyoka and Musokonyi 2002).

Habitat and Ecology

Habitat and Ecology
The habitat of this species is the montane and submontane forest in Eastern Zimbabwe and probably in neighbouring Mozambique. This includes miombo type woodlands. Albizia adianthifolia (Fabaceae) is thought to be a larval host-plant (Pringle et al. 1994).

Justification

Charaxes alpinus is a submontane/montane butterfly of the eastern mountains of Zimbabwe, known from the Chimanimani and VumbaMountains. The extent of occurrence (EOO) is thus limited to a few thousand km2 and the area of occupancy (AOO) is still less. However, its habitat is primarily miombo woodland in the eastern highlands which is unthreatened and fairly extensive within the EOO (Nyoka and Musokonyi 2002). There is no evidence of decline or extreme fluctuation in the AOO or EOO and so this species does not qualify as threatened under criterion B. However, both known localities are national parks with plenty of the appropriate habitat and it is likely that species is more widespread in adjacent areas of Mozambique that have not been studied. There is no reason to expect any population declines and the species is probably stable within its rather small area of occupancy. It should be a species of Least Concern as long as the habitat is maintained (A. Gardiner pers. comm. 2008).

Threats

Major Threats
The main known populations of this butterfly are found in national parks and there is a large amount of suitable habitat available (T.B. Larsen pers. comm. 2008) and so the most likely threat of deforestation is not currently a major threat to this species.

Conservation Actions

Conservation Actions
The two main known populations of this species are found in national parks (T.B. Larsen pers. comm. 2008). No other conservation actions are required although further research is needed into the distribution of this butterfly in Mozambique.
