Our aim is to encourage an interest in arachnids – especially spiders and scorpions - and to promote this interest and the study of these animals by all suitable means. Membership is open to anyone – people interested in joining the club may apply to any committee member for information. Field outings, day visits, arachnid surveys and demonstrations, workshops and exhibits are arranged from time to time. A diary of events and outings is published at the end of this newsletter. Mission Statement “The Spider Club provides a fun, responsible, social learning-experience, centred on spiders, their relatives and in nature in general.” Our Contact Details www.spiderclub.co.za P.

Then let the editor have some feedback. If you don’t we might just drop a Parabuthus granulatus down your T-shirt! Talking of which we have scads of bright Spider Club T-shirts, caps, waist belts, 5 litre sweetie jars (to house live arachnids so the kids cannot get at them to abuse them) and if you do go out there, please advertise the club by wearing our regalia. It’ll cost you – of course! If you feel out of your depth with spiders, scorpions, solifuges, whip spiders, false scorpions, etc., the best way to learn about them is HANDS ON. That means: join in club activities and learn in the field or at sorting or identification workshops. Check the diary at the end of this newsletter against your diary and make a plan to join in. Of course if you don’t want to, not to worry, we will take your money and send you a newsletter every now and then, but if you want to get your money’s worth, GET INVOLVED, it’s your loss if you don’t. PS I LOVE being an old auntie, I can moan at people and they often don’t answer back. Arachnologically yours, Astri From the Editor: This quarter we have a special edition, containing two long articles. The subject of the first is a discussion on parasitism by wasps on spiders, written and researched by Tony Rushton. We felt that, to do it justice, we could not shorten it, or cut it into two parts. Secondly, Alistair Mathie has contributed the first instalment of “Know your scorpions”. We hope that you enjoy both contributions. Thanks to Tony and Alistair for these fine efforts. Alistair has asked for anyone who has been stung by a scorpion to give him details of the experience. See his advertisement in this edition. As a result of publishing two long articles in this edition, we have had to carry a fair amount of material over to the next issue. However, we still need your contributions! Once again, we have to moan about the lack of support by Spider Club members for the various events arranged on their behalf. Fortunately, non-members support our outings, but we would like to see more of you! You don’t know what you are missing! And please keep sending us your contributions for YOUR newsletter! Lloyd Grobler has been co-opted on to the committee, as our representative in the “South”. He is presently doing a survey on the Klipriviersberg arachnida. Best spider regards Joan Spider Club News March 2009 Page 3 Events Reports Fascinated by Spiders – November 2008 Astri presented talks "Fascinated by Spiders" at the regular Nedbank/Africa Geographic Reader evenings in Durban on 12 November, in Sandton on 20 November, in Cape Town on 27 November, and at the Lowveld National Botanical Garden on 21st November 2008. All the talks were extremely well-attended and well received. Lloyd and Joan attended the Johannesburg session. The interesting talk was supported by fine photographs taken by John Leroy, and there was quite a lengthy Q & A session afterwards, with a lot of interaction from an enthusiastic and curious audience. The presentation in Durban was followed by a field trip to Krantzkloof Nature Reserve on 15 November. The Cape Town presentation was held in the magnificent BoE Head Office overlooking the yacht basin at the V&A Waterfront in Cape Town on 27 November followed by field trip with Norman Larsen on 29 November to Kenilworth Racecourse conservation area (right). (Ed. Astri, how about field reports for these trips?) (above photo by John Leroy) We recommend that you attend the Reader Evenings, and the new season should be starting soon. The evenings cover all sorts of topics related to nature, the environment and conservation issues, and Nedbank supplies delicious suppers and wines to make the evenings even more enjoyable. Joan Faiola Spider Club Outing to Rand Water Board – 24 January 2009 On 24 January, some of the Spider Club members and a few members of the public visited the Rand Water Reserve at their head offices in the south of Johannesburg. Even though we were only a handful, we had an awesome and exciting time (especially Steve☺). The reserve has something to it which really makes it a fascinating place. We found all sorts of cool things and to mention just a few, a very beautiful young baboon spider (possibly a young Harpactirella), a not so common velvet spider in the family Eresidae – probably a male Gandanameno, two harvestmen (Opiliones), and some Spider Club News March 2009 Page 4 Opistophthalmus pugnax amongst many other interesting creepy crawlies and spiders! After collecting and bringing some specimens back to the lapa, Astri helped us to identify what we have found, before releasing them back into the wild. One really learns a lot from joining these outings and they are a must for any arachnophile! The Spider Club would also like to thank Rand Water and the reserve curator Sizwe for their kind hospitality and for letting us use their reserve. Lloyd Grobler (Photo: Joan Faiola) Spider identification course- 21 February 2009 On 21 February, Astri conducted another of her beginners’ spider identification courses, at Kloofendal Nature Reserve. As usual, it was very well attended, and well presented. Astri is really learning how to use her computer and projector to their fullest! Lloyd and I were there to assist Astri, but of course, we learned a lot too. The first part of the course was theoretical, and included comprehensive notes for participants to study on their own. Then we went into the reserve to learn how to find and collect specimens. We found some interesting animals, and went back to the lecture room to have a better look under the microscopes. Joan Faiola Butterflies and Spiders at Borakalalo 13- 15 March 2009 Story and Photos by Joan Faiola The BTA Club, represented by Monika O’Leary, invited the Lepidopterist Society and the Spider Club to send their experts to a BTA Outing at Borakalalo. The presence of the Honorary Officers made it possible for the participants to wander anywhere in the reserve – a rare privilege. On Friday evening, we found a number of Araneus apricus near the river. We also found some long-jawed spiders in the genus Tetragnatha. On Saturday morning, we wandered along the road past Moretele campsite, where we stayed, looking for interesting specimens. We found many specimens, including lots of crab spiders (Thomisidae), jumping spiders (Salticidae), sac spiders (both Miturgidae and Clubionidae) and Lynx Spiders (Oxyopidae), and just a few of the big Nephila spp. Not to mention some beautiful butterflies. Butterflies were in great abundance and variety, including Charaxes spp, and many others. Note: net techniques differ vastly between butterfly and spider collecting! A full list of species will be made available soon. In the afternoon, we drove to the grassland/wetland opposite the top picnic site, where we were allowed to wander around at will. We found many interesting spiders, highlights being the lovely banded garden spider Argiope trifasciata in abundance, and a beautiful large green Lynx spider Peucetia sp. guarding her young.
