This large species inhabits the Mexican Plateau and the Cordillera
Volcanica, but not the Sierra de Coalcoman, where apparently it is
replaced by _Sceloporus bulleri_. _Sceloporus torquatus torquatus_
usually is found in pine or pine-fir forests at elevations between 1450
and 3000 meters. In many places it is almost entirely arboreal, but in
areas where there are many fallen trees or rock fences and rock piles,
many individuals have been found on the ground near the rocks or logs.
In the coniferous forests this species is associated with _S. grammicus
microtepidotus_ and _S. aeneus aeneus_.

The distinction made by Smith (1938:572) between the subspecies _S.
torquatus torquatus_ and _melanogaster_ is slight. Individuals with pale
bluish spots are found throughout the range of the species in Michoacan;
spotting is especially evident in the young. Individuals having an
incomplete nuchal collar have been found at Maravatio and at Zinapecuaro
in the northern part of the state; in this character these specimens
resemble _S. torquatus melanogaster_, which is found to the north from
Guanajuato to Zacatecas and San Luis Potosi.
