Hi,
I found this spider and her young in a messy web in the branches of a small gum tree in my garden. I am curious to know what type they are. Photo taken 20/01/11.
Many thanks

Cobweb Spider

Hi Tanya,
We really love your photograph, which we believe shows a Cobweb Spider or Comb Footed Spider in the family Theridiidae
with her brood.  The family includes the notoriously venomous Red Back Spider in Australia and Black Widow in North America, but most of the members in the family are quite benign.  It appears that the Spiderlings in your photo are taking advantage of feeding off of a Fly that has become ensnared in their mother’s web.  We were unable to conclusively match your Spider to any of the Comb Footed Spiders on the Brisbane Spider website.

Hi Daniel,
Many thanks for your quick response, very interesting to find out what the spider is, she is still in her curled up leaf with her babies today.
Kind regards
Tanya
