The poisonous black widow spider, under pressure in SoCal from the brown widow, which hails from Florida.
Last week, I ran an interview with Rick Vetter, a spider expert at UC Riverside, who told us how the brown widow spider, an invasive species, is pushing the native black widow spider out of Southern California's urban areas.
Listener Dennis McCoy called to complain. You never asked about the webs of the two spiders, he said. Are they different? Is the brown widow's web as sticky as the black widow's?
