Redbelly Snake (Storeria occipitomaculata)
Redbelly snakes are North Dakota's smallest snakes, as they seldom exceed 12
inches in length. Their name is appropriate as their bellies have a bright red
to salmon color. These snakes are seldom seen due to their small size, shyness,
and nocturnal habits. Redbelly snakes vary from light to dark brown, gray or
chestnut. This coloration also makes the redbelly snakes hard to see in their
habitat. They live in or around woodlands, and prefer the margins of woodlands
for foraging. They hide during the day under stones, boards, rotten logs, or
other forest cover and come out toward evening. Their diet is very specific.
They will feed on small earthworms and beetle larvae, but prefer slugs.
These small snakes hibernate in ant mounds during the winter. They mate
in the spring and the females give birth to one to 21 young in a litter.
