Agriocnemis gratiosaGRACIOUS WISP

Identification

Very small size

Length up to 26mm; Wingspan attains 28mm.

Most similar to Agriocnemis falcifera (White-masked Wisp). The Gracious Wisp can be told apart by its round postocular spots that are not joined by a thin line. Additionally the male Gracious Wisp lacks the white moustache of the White-masked Wisp. These two species are the largest Southern African wisps which helps to separate them from the other smaller species.

Habitat

Associated with the fringes and clearings of coastal, swamp and dune forests. Occupies damp, grassy areas connected to slow-moving streams, pools, pans and marshes. Favours sites with a rich growth of tall grasses, ferns and other herbaceous plants. Often found in shady areas with dappled light.

Habitat – Near Kosi Bay, KwaZulu-Natal

Behaviour

An unobtrusive species that hides low down among rank vegetation.

Most active from October to April. See Phenology below.

Status and Conservation

Scarce and very localised. In the IUCN Red List of Threatened Species it is listed as Vulnerable in South Africa, but of Least Concern overall.

Distribution

A species of East and Southern Africa.

It has been recorded in Botswana, the Democratic Republic of the Congo, Kenya, Madagascar, Malawi, Mozambique, Namibia, South Africa, Sudan, Tanzania, Uganda, Zambia, and possibly Burundi.

In South Africa it is restricted to the coastal region of NE KwaZulu-Natal, reaching as far south as Amanzimtoti. Also found locally at a few scattered sites in the Lowveld of Mpumalanga and Limpopo.

Below is a map showing the distribution of records for Gracious Wisp 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.
