PDFs are now available. We truly appreciate all the help that we got last year from all you citizen scientists.  It really added a lot of geographic breadth to our study.

2011 Brown Widow Research Results

Last year on this website, we had a request for spiders and egg sacs for two research projects regarding a search for egg sac parasites and to document the microhabitat choices of the brown widow in southern California. This research has resulted in two publications. Your participation was greatly appreciated.
