Female drider

Driders are bloodthirsty creatures that lurk in the depths of the earth, seeking warm-blooded prey of any kind.

All drow must pass a special test set upon them by their goddess Lolth. Those who fail become doomed to suffer existence as the half-drow, half-spider drider. Drow and drider hate one another passionately.
