The range of Tegeticula closely matches the extant distribution of their yucca hosts. This includes the extended ranges of yuccas in interior eastern North America, where European settlers introduced yuccas over the last 150 years. The northern limit of the genus is now in southern Alberta and Ontario in Canada. The southernmost records are from Tehuacan in Puebla, Mexico (Davis 1967).
Riley shipped larvae to Europe in an attempt to introduce yucca moths, but there is no report of success.
