This species has been collected in oak, pine-oak, and fir forests at
elevations of 1900 to 2450 meters on the mountains rising from the
Mexican Plateau. It does not seem to be so abundant as _Conopsis
biserialis_. Sufficient ecological data to determine differences in
habitat between the two species have not been compiled.

Apparently this snake is uncommon in Michoacan. It has been found only
at elevations of 1900 to 2200 meters in pine and pine-oak forests on the
mountains rising from the Mexican Plateau.

The few specimens indicate that in Michoacan, as elsewhere on the
Pacific coast of Mexico, this species is restricted to forested regions
on the coastal plain. It does not occur in the Tepalcatepec Valley.
The coloration, in life, of a juvenile (UMMZ 114604) is as follows: The
dorsum is uniform pale grayish tan on posterior one-third of body and on
tail; anteriorly there are pale grayish tan middorsal blotches separated
by grayish white interspaces, which are about one-half the length of the
blotches. Posteriorly the blotches are less distinct, fading into the
uniform grayish tan ground color of the posterior part of the body. The
blotches extend laterally onto the fourth and fifth scale rows. Large
squarish lateral intercalary blotches of darker brown interconnect with
the dorsal blotches. The top of the head is pale olive-brown; a dark
brown postorbital stripe extends from the eye to the posterior edge of
the last upper labial. The labials, chin, and ventrals 1-30 are creamy
white, changing to a dusty cream-color posteriorly; the chin and
ventrals 1-30 are heavily spotted with dark brown. The iris is a
cream-color above and chocolate brown below; the tongue is blue.
