Below, a Brown Widow Spider waits for prey in its seemingly haphazard tangle web, the typical design of all comb footed spider webs.  A recent spider survey in the GNG found well over 100 Brown Widows, and not a single Black Widow.  It is not well understood why the alien Brown Widow out-competes its native cousin the Black Widow, or why this replacement of spider species is happening so quickly.  What is known, for good or bad, Brown Widow Spiders are now well established in the Los Angeles Basin and are here to stay.
