Drakensberg Malachite (Chlorolestes draconicus)

Chlorolestes draconicus, the Drakensberg Malachite, is a species of damselfly in the family Synlestidae. This species has a restricted range in the Drakensberg mountains of Lesotho and South Africa. Its conservation status has been assessed as Least Concern as much of its range falls within the uKhahlamba / Drakensberg Park.

The above photo (by Riëtte Griesel) can be viewed in OdonataMAP here. Below is a map showing the distribution of records for Drakensberg Malachite in the OdonataMAP database as at February 2020.

The next map below is an imputed map, produced by an interpolation algorithm, which attempts to generate a full distribution map from the partial information in the map above. This map will be improved by the submission of records to the OdonataMAP section of the Virtual Museum.

Ultimately we will produce a series of maps for all the odonata species in the region. The current algorithm is a new algorithm. The objective is mainly to produce “smoothed” maps that could go into a field guide for odonata. This basic version of the algorithm (as mapped above) does not make use of “explanatory variables” (e.g. altitude, terrain roughness, presence of freshwater — we will be producing maps that take these variables into account soon). Currently, it only makes use of the OdonataMAP records for the species being mapped, as well as all the other records of all other species. The basic maps are “optimistic” and will generally show ranges to be larger than what they probably are.

These maps use the data in the OdonataMAP section of the Virtual Museum, and also the database assembled by the previous JRS funded project, which was led by Professor Michael Samways and Dr KD Dijkstra.
