Kite Spiders: South Africa

Kite spiders are diurnal Araneidae or "orb-web" spiders which means that during the process of making a web, the spider will use its own body for measurements.

Gasterocantha sanguinolenta
These spiders are small (8-10 millimetres long), with 4 species in South Africa. The Araneidae occupies a niche not utilized by other spiders: the aerial passage amongst vegetation in the path of flying insects.
The diurnal orb web spiders continually repair their webs, usually using them for a few of days. The web cannot be used indefinitely as it dries and loses its capture ability and insects will no longer stick to it.
