Barn spider

The barn spider was a species of spider native to North America. At least one such specimen resided in the Jennings house, where it was found by the Jennings family. Ross Jennings, a lifelong arachnophobe, petitioned his wife to take the little spider to their nearby barn, where that specimen mated with a much larger specimen of a new species that had been accidentally transported to the site.
