Family Coenagrionidae

Agriocnemis pinheyiPINHEY’S WISP

Identification

Very small size

Length up to 21mm; Wingspan attains 26mm.

Most like Agriocnemis exilis (Little Wisp). They are similar in size, and are in fact the two smallest damselflies in the region. Pinhey’s Wisp has an unbroken green line across the face and an incomplete green line across the prothorax. The Little Wisp shows the exact opposite, having a broken green moustache and an unbroken green line on the prothorax.

Females are variable and best told by their association with the males.

Habitat

Inhabits dense grass and sedge margins of pools, dams, seeps and marshes, as well as the fringes of slow moving streams. Found at fairly high altitude from 1200m to 1600m a.s.l.

Behaviour

Usually perches near vertically on a sedge or grass stem. Typically low down close to the water. Unobtrusive and easily overlooked.

Most active from October to April. See Phenology below.

Status and Conservation

Fairly common but localised. Listed as of Least Concern in the IUCN Red List of Threatened Species.

Distribution

Occurs in Southern, Central and East Africa. Found inland, in the Eastern parts of South Africa from the Eastern Cape to Limpopo.

Below is a map showing the distribution of records for Pinhey’s 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.

Megan Loftie-Eaton is our communications, social media and citizen science coordinator. Prior to her work for the BDI, she coordinated OdonataMAP, the Atlas of African Odonata. Sally Hofmeyr has many years' experience in the academic world, writing her own material and editing the work of others. Her academic background is in the natural sciences: her PhD and first postdoc in ornithology and environmental change (Animal Demography Unit, University of Cape Town). Ryan Tippett is an enthusiastic contributor to Citizen Science and has added many important and interesting records of fauna and flora. He has been a member of the VMU since 2014 and has currently submitted over 11000 records. He is also on the expert identification panel for the Odonata Map project. Prof Les Underhill has been Director of the Animal Demography Unit (ADU) at the University of Cape Town since it started in 1991. Although citizen science in biology is Les’s passion, his academic background is in mathematical statistics.
