How do young Black Widow spiders leave the nest and go out on their own?
Black widows are one of many kinds of spiders that disperse by "ballooning", whereby the new born spiderling releases some silk into a breeze and then allows the wind to carry the strand of silk, with the spider on it, to wherever the wind shall go. This was nicely depicted years ago in a cartoon movie called "Charlotte's Web", where at the end of the movie the new baby spiders took off on their flight and the momma spider, as I recall, passed away - a bit morose for a Disney movie but pretty accurate, although the females do not necessarily die after producing their next generation.
