What is the traditional method of infusing liquor with a worm, and what significance does the worm hold in this process?

The traditional method of infusing liquor with a worm involves placing a larvae of the Hypopta agavis moth into a bottle of mezcal. The larvae feeds on the agave plant, fermenting the sugars, and eventually dies in the alcohol. The worm is believed to enhance the flavor and potency of the liquor, though it is more of a marketing gimmick rather than a true indicator of quality.
