Just in time for Halloween
This audio slideshow introduces a spider that I found in an outside crevice of my window. I believe it is a bola spider, a species of spider featured in the David Attenborough/BBC video “Life in the Undergrowth.”
These spiders position themselves on the underside of a leaf (or window frame), dangling a string of silk with a sticky ball on the end. They then attract moths with pheromones or chemical scents that attract the moth. When a moth comes close enough, the spider swings the ball in hopes of attaching the moth to the sticky ball.
In summer, our windows attract a lot of moths, perfect habitat for a bola spider.
