058 Genus Kedestes Watson AFROTROPICAL BUTTERFLIES. MARK C. WILLIAMS. http://www.lepsocafrica.org/?p=publications&s=atb Updated 16 January 2021 Genus Kedestes Watson, 1893 Rangers Proceedings of the Zoological Society of London 1893: 96 (3-132). Type species: Hesperia lepenula Wallengren, by original designation. The genus Kedestes belongs to the Family Hesperiidae Latreille, 1809; Subfamily Hesperiinae Latreille, 1809, Tribe Hesperiini Latreille, 1809. Other genera in the Tribe Hesperiini, are Lepella, Prosopalpus, Tsitana, Fulda, Gorgyra, Gyrogra, Teniorhinus, Flandria, Hollandus, Xanthodisca, Acada, Rhabdomantis, Osmodes, Parosmodes, Osphantes, Acleros, Paracleros, Semalea, Hypoleucis, Paronymus, Andronymus, Malaza, Perrotia, Ploetzia, Moltena, Chondrolepis, Zophopetes, Gamia, Artitropa, Mopala, Pteroteinon, Leona, Caenides, Monza, Melphina, Melphinyet, Noctulana, Fresna, and Platylesches. Kedestes (Rangers) is an Afrotropical genus of 14 species. Apparently closely related to the genus Ampittia (Kielland, 1990d). The majority of species occur in eastern and southern Africa. Only two species are found in West Africa. Morphologically they are of diverse appearance and Larsen (2005a) thinks that the genus may be paraphyletic. The larval hosts are grasses (Poaceae) in 8 of the 14 species in which they are known. *Kedestes barberae (Trimen, 1873)# Freckled Ranger Images of a female Barber’s Ranger (Kedestes barberae) Images courtesy Steve Wooshall Cyclopides barberae Trimen, 1873.

Alternative common name: Barber’s Ranger; Gevlekte wagtertjie (Afrikaans). Type locality: [South Africa]: “Stormbergen, Cape Colony”. Holotype (female) in the Natural History Museum, London. Diagnosis: Antennal club thick; forewing upperside with white spots; underside hindwing with characteristic, bold, irregular shiny white streaks (Kielland, 1990d). Distribution: Tanzania, Zambia, Mozambique (Congdon et al., 2010), Zimbabwe, South Africa, Swaziland (Duke et al., 1999), Lesotho. Habitat: Grassland, from sea level in the Western Cape Province to 2 800 metres in Lesotho. Often in marshy areas or along stream banks (Pringle et al., 1994). Most of the former habitat of subspecies bunta, on the Cape Flats, has been destroyed by urbanization and invasion by alien vegetation (Pringle et al., 1994). Habits: Flies rapidly, close to the ground, around grassy areas, frequently settling on grass blades (Pringle et al., 1994). Both sexes are strongly attracted to flowers. Males occasionally hilltop but more usually establish territories near stands of the larval host plants. Kielland (1990d) noted that they perch for long periods on bare ground once the sun has warmed it. Flight period: Double-brooded, flying in October and November, and again in March and April. It is most abundant in October-November but has been found as early as August near Port Elizabeth (Pringle et al., 1994). The subspecies bunta is on the wing in September and October (Pringle et al., 1994). Early stages: Clark, in Dickson & Kroon, 1978: 250; plate 23 [as Kedestes barberae; Port Elizabeth, Eastern Cape]. “Egg: Laid singly on grass; 1.3 mm diameter by 0.8 mm high. Milk-white, changing to pale yellow and then salmon and finally brown as larva takes shape inside the egg. There are some 60 very faint and ill-defined longitudinal ribs from the base to about a third of the way up the side, with minute indentations between them. Incubation period 15 days. The shell is sometimes eaten. Larva: 1st instar 3.25 growing to 6.5 mm in 10 days; 2nd instar 6.5 growing to 11 mm in 14 days; 3 rd instar 11 growing to 16 mm in 14 days; 4 th instar 16 growing to 23 mm in 15 days; 5th instar 23 growing to 33 mm in 20 days. The duration of the instars is very variable. Sometimes there is an additional instar between the normal 4th and 5th, attaining a length of 26.5 mm. Larvae draw the edges of grass together to form tubes, in which they live. They feed on the upper end of the blades. Pupation takes place within the grass tube. Pupa: 16.5 mm. There are no cremastral hooks. Emergence after some 23 to 29 days. There is more than one brood a year in the case of some of the races of this butterfly, but not 2 in all of them. K. barberae bunta Evans, from the Cape Peninsula, is certainly single-brooded. The identity of the present race remains undetermined. Recorded from eggs and larvae from Summerstrand, near Port Elizabeth.” Larval food: Imperata cylindrica (L.) Raeusch. (Poaceae) [Murray, 1959; Dickson & Kroon, 1978: 193; as Imperata arundinacea].

  • Driftsands Nature Reserve Complex PAMP
    EXECUTIVE SUMMARY The Driftsands Nature Reserve is situated on the Cape Flats, approximately 25 km east of Cape Town on the National Route 2, in the Western Cape Province. The reserve is situated adjacent to the Medical Research Centre in Delft and is bounded by highways and human settlement on all sides. Driftsands is bound in the northwest by the R300 and the National Route 2 and Old Faure road in the south. The northern boundary is bordered by private landowners, while the eastern boundary is formed by Mfuleni Township. The Nature Reserve falls within the City of Cape Town Metropolitan Municipality. The reserve experiences a Mediterranean-type climate with warm dry summers, and cool wet winter seasons. Gale force winds from the south east prevail during the summer months, while during the winter months, north westerly winds bring rain. Driftsands Nature Reserve represents of one of the largest remaining remnants of intact Cape Flats Dune Strandveld which is classified as Endangered, and harbours at least two Endangered Cape Flats endemics, Muraltia mitior and Passerina paludosa. The Kuils River with associated floodplain wetlands, dune strandveld depressions and seeps are representative of a wetland type that has been subjected to high cumulative loss, and provides regulatory ecosystem services such as flood attenuation, ground water recharge/discharge and water quality improvement. The site provides access for cultural and/or religious practices and provides opportunities for quality curriculum based environmental education. Driftsands Nature Reserve is given the highest priority rating within the Biodiversity Network (BioNet), the fine scale conservation plan for the City of Cape Town.

  • BUTTERFLIES of the CHYULU RANGE. a Systematic List of the Species Taken by the Museum Expedition to the Hills
    PART 3. BUTTERFLIES OF THE CHYULU RANGE. A systematic list of the species taken by the Museum Expedition to the Hills. April-July, 1938. By V. G. L. VAN SOMEREN,F.L.S., F.R.E.S., Etc. INTRODUCTION. The following account of the Lepidoptera (Rhopaloc.era) taken by members of the Museum Expedition to the Chyulu Range, is mainly a systematic list of the species obtained. At the time of the visit, April to July, 1938 (that is just toward the end, and after the long rains) insect life was remark• ably scarce, and although systematic search was made over all portions of the hills from 3,000 to 7,000 feet, at no time were butterflies numerous. The material taken can be considered representative of the range for that particular season, but there is little doubt that insect life would be more plentiful just after the short rains, as it undoubtedly is on the surrounding plains, especially in the Kibwezi- Voi areas. In spite of the paucity of insect life, certain new records have been established, thus Papilio hornimani is recorded for the first time from within Kenya boundaries, although known for many years to inhabit the forests of Mt. Kilimanjaro. Charaxes ful• vescens nr. acuminatus, also of Tanganyika, was taken on the range. Two new races of Liptenines of the genus Pentila are recorded, whilst a new ACTaea,a new Papilio, and a new race of Amauris are described. The Lepidoptera collected have a definite relationship to the vegetational zones and the distribution of certain plant species at various altitudes and portions of the hills.

  • Aquatic Ecological Specialist Assessment for the Proposed Upgrades to the Cape Flats Wastewater Treatment Works Including a New Access Road, Cape Town
    AQUATIC ECOLOGICAL SPECIALIST ASSESSMENT FOR THE PROPOSED UPGRADES TO THE CAPE FLATS WASTEWATER TREATMENT WORKS INCLUDING A NEW ACCESS ROAD, CAPE TOWN APRIL 2021 Prepared for: Prepared By: Ms Toni Belcher and Dana Grobler PO Box 455, Somerset Mall, 7137 Tel: (021) 851 0555 Email: [email protected] Page | ii EXECUTIVE SUMMARY The City of Cape Town (CCT) is proposing to upgrade the sludge handling facility at the Cape Flats Wastewater Treatment Works (WWTW) in Cape Town. The proposed new Biosolids Beneficiation Facility (BBF) will be constructed within the footprint of the WWTW and will replace the existing Thermal Drying Plant. The BBF will treat sludge from the WWTW as well as other WWTW that will need to be transported to the BBF. The project thus includes consideration of a new access road. The potential for the new access road to serve as a multipurpose access road serving not only the WWTW but also the False Bay Nature Reserve (FBNR) and Pelican Park Phase 2 housing development was identified. The access road route alternatives identified are: • Option 1 and Option 2 which share an access point with the Coastal Park Landfill site and access the WWTW from the west; • Option 3 and Option 4 which will access the site via Strandfontein Road (from the east) and transverse portions of the FBNR; • Option 5 which will traverse the proposed (PPP2) housing development (north-east of the WWTW) and serve as a multipurpose access road to the WWTW and FBNR; and • Option 6 which is a refinement of Option 5 and is the final preferred route.

Edge School of Environmental Sciences and Development, Private Bag 6001, North-West University, Potchefstroom, 2520 ([email protected]) Introduction The conservation of insects generally and of butterflies in particular has gained momentum in the last few decades in many parts of the world as recent publications show (Pullin, 2005; Samways, 2005; New, 2009; Van Swaay et al., 2009; McGeoch et al., 2011). South Africa has not lagged far behind in this enterprise, and following the establishment of the Lepidopterists’ Society of Africa (LepSoc) in 1983 there have been many efforts to alert the authorities and the public at large to the plight of our butterflies (e.g. Henning, S.F. & G.A., 1989, 1996; Edge, 2005a; Henning et al., 2009). LepSoc also participated in the Southern African Butterfly Conservation Assessment (SABCA) project, from which the publication of a revised Red List for butterflies in southern African is pending (Mecenero et al., in prep.). This will provide butterfly conservation with an even sounder base of scientifically accumulated data. LepSoc has also gained increasing expertise in butterfly conservation, following research and successful conservation efforts with butterflies such as the Brenton Blue (Orachrysops niobe) (Edge, 2011), the Roodepoort Copper (Aloeides dentatis dentatis) (Deutschländer & Bredenkamp, 1999), and the Heidelberg Copper (Chrysoritis aureus) (Henning & Roos, 1999). Mecenero et al. (in prep.) identify 61 taxa as threatened in terms of the IUCN (2010) categories and criteria (Table 1). Drawing inspiration from SANBI’s successful Custodians of Rare and Endangered Wildflowers programme (CREW, 2009), LepSoc has decided to launch a programme called COREL (Custodians of Rare and Endangered Lepidoptera), to promote and ensure the conservation of all butterflies and moths Red Listed as threatened in South Africa.
