Long Lobed Spider - Cyclosa bifida ?

This page contains pictures and information about Long Lobed Spiders that we found in the Brisbane area, Queensland, Australia.

Body length 10mm 

 

This spider has elongated abdomen minor lobes on it.

On Nov 2009, we found that this spider is quite common in Boondall Wetlands.  

 

 

By carefully inspected the debris stabilamenta, it includes the egg-sacs, both on the upper side and the lower side.  

 

 

Small Long Lobed Spider does not make debris stabilamenta. It makes messy stabilamenta.
