Hi,
While driving through the Addo Park, we saw many trees and shrubs covered in a web-like matter. It looks as if the web has pulled the branches together to form a large nest inside. On closer scrutiny we noticed that the nest was full of small holes, either for allowing those inside to get out or those on the outside to get in.
By the size of the web, it must be one massive spider.
Does anyone know what makes these webs?

Hi lilowen and Welcome!

From your description, it sounds like what your saw were nests of community spiders. 8)

Hi lilowen,

These are nests of a moth which lays its eggs in the gwarrie bush (Euclea undulata). The caterpillars live inside this nest and eat the gwarrie leaves. While they are inside the nest, they have better protection from birds etc that would usually prey on the caterpillars. We are not sure exactly what species of moth this is, but an entomologist confirms it belongs to the Pyralidae or Ethmiidae family.

Hi Megan and thanks for the reply.
Since my original post, we have been back to Addo again and I still wanted to make another comment about the nests. I had noticed that they were mainly, I thought, in the gwarri bush and that the leaves around the nest on the bush were all bare. I found that this would be strange for spiders.
Now we know.
Many thanks. :)
