There are two subspecies of night snakes found in the range of this work. I am told that work is underway to combine them into one species.
TEXAS NIGHT SNAKE
Hypsiglena torquata jani
The Texas night snake is found throughout the wstern 2/3 of the state, except for the Big Bend region where the spotted night snake occurs.
It is a small snake, seldom found over 12 or 14 inches. The females tend to be larger than the males. The largest one I have found was a female which was 23 inches long. She laid 3 eggs, two of which hatched. The hatchlings were 6 1/2 inches long.
Their primary prey is lizards, but insects, worms and smaller snakes are reported to be taken.
This specimen is from near Loma Alta, Val Verde County.
This specimen is from the Delaware Mountains in Culberson County.
