rapidly. This snake is very secretive and very fossorial and rarely seen above ground during the day unless it is forced out by heavy rains. The mole kingsnake is mainly nocturnal and commonly seen on paved roads at night. This species has been observed to ingest prey whole and headfirst, even prey with a diameter over 90% of the diameter of the snake's head. This is thought to be an inherited behavior.

Reproduction

Male and female mole kingsnakes mate around May–June during late spring to early summer. Females leave behind pheromone trails for males to sense through their forked tongues. Mating events in a laboratory setting were recorded to have lasted over two hours. After mating, females choose their nesting sites underground or in rotting logs and leave their 10-12 eggs to hatch in the summer. The mother does not stay behind to nurture her offspring, usually leaving right after she laid the eggs. It takes about ten days for the hatched snakes to be fully independent. The hatchlings and eggs of ''L. rhombomaculata'' are both of smaller average size than those of '' L. calligaster''.
