Community Nest Spiders

Adult spiders of most species are solitary and devote the greater part of their lives to catching prey, which can include prospective mates. Should the opportunity arise, they tend to eat mates, brothers, sisters, parents and young, leaving a single, fat, well-fed individual!
  Not all spiders are anti-social, though. Community nest spiders, in the genus Stegodyphus, such as Stegodyphus dumicola, are our only truly social spiders in South Africa. They live in communities, co-operating in prey capture and brood care. When a large insect lands in the web, it invites a heaving scrum of spiders, which eventually overpowers most insects. The nest - consisting of strong, hard, cardboard-like silk - starts off small but is enlarged as the colony grows. It has numerous holes and passageways. Large colonies can cover an entire tree in silk.

According to Astri Leroy, having this colony on the Common is really lucky as it is difficult to find them anywhere on the Cape Peninsula because Argentine ants are thought to have more or less wiped them out in greater Cape Town.

Banded Garden Orb-web Spider

Banded Garden Orb-web Spider (Argiope trifasciata).

This beautiful spider belongs to the Araneidae family of spiders. Argiope is one of the most familiar genera of orb-web spiders. Being diurnal, garden spiders are colourfully marked, the carapace silver and the legs banded. The aposematic (warning) yellow and black colouration of the abdomen remind birds that they are unpalatable. The Argiope web normally has two zig-zag bands of silk radiating outwards from the hub (centre) to the bottom corners of the web. There may be four of these bands in some species while some juveniles may construct a spiral. These are called “stabilimenta” and serve various functions: they stabilize and strengthen the web, make the web visible perhaps serving as a decoy for birds, or also to reflect ultraviolet light thereby deceiving and attracting insects.

How you can join the CREW and learn more about our rare and endangered plants

The Friends of Meadowridge Common will be holding their AGM for 2015 on Wednesday 25 February in the community hall of the Meadowridge Library (click here for map) at 7h30 pm. The guest speaker will be Ismail Ebrahim of the South African National Biodiversity Institute's Custodians of Rare and Endangered Wildflowers (CREW) programme. CREW involves volunteers from the public in the monitoring and conservation of South Africa's threatened plants. Anyone can get involved - and CREW provides general plant identification courses as well as field training - so come along to the AGM and find out more. The programme is a partnership between SANBI and the Botanical Society of South Africa (BotSoc). For more information on CREW, click here.
Meadowridge Common has many of its own rare and endangered plants, and Fiona Watson, the Friend's Botanical Officer, will also be giving an update on the flora of Meadowridge Common.
Refreshments will be served and secure parking provided.
Please phone Fiona Watson at 021 712 0696 for more information.   
The Flats Silkypuff, (Diastella proteoides) on Meadowridge Common. This species was probably common and widespread, but it is now restricted to a few remnant patches of lowland fynbos. See Red List.

We would be most grateful if you could share your bird-sightings on the Common on the Facebook page, iSpot or contact the Friends of Meadowridge Common at Meadowridgefriend@gmail.com. You could also post on the ADU site "My Bird Patch" -  http://mybirdpatch.adu.org.za. The Common (including the football fields) is already on the site. MyBirdPatch is a way to collect bird information for small patches that are regularly visited by observers. It would be great to use this as a way for people to log their sightings. They will need to register as an observer with the project but can then add sightings for the common and any other public patches that have been registered. To register as an observer click on 'Register' and to find out more about how MyBirdPatch works click on 'Help" and download the "20 easy steps to getting started" document.

The Richtersveld - an illustrated talk

The Friends of the Meadowridge Common invite all to a talk on the Richtersveld by Michael Borgstrom, a local resident who has a keen interest in the flora of that region and has visited there many times. He will present his experiences there, illustrated with slides. The evening will be held at the Meadowridge Library on 20th October at 7.30 and there will be secure parking. 
Fay Howa, the Common's Conservation Officer, will also present a short, illustrated account of her programme for schools to learn about Leopard toads in the environment.
The talk is free, but non-members will be asked for a donation towards the Friends of Meadowridge Common. Contact Fiona Watson at 021 712 0696 for information.
